I'm going to try and persude you away from the Canon in this forum. :D

I would say check out these used.

Nikon d40
Nikon d40x
Nikon d50
Nikon d80
 
A used f/2.8 zoom by Sigma or Tamron (zoom range 17/18mm to 50/55mm) would be better for learning and general photography than the "kit" 18-55 lens, as the kit lens's slow (f/3.5-5.6) aperture limits your ability to blur out backgrounds, and you'll need to crank up the ISO (sensor sensitivity) when you're in poor light - possibly even more than on a compact camera with a f/2-2.8 zoom (granted, only the top-end compacts have this) (and the DSLR image quality at e.g. ISO 800 will probably be better than the a compact camera at ISO 200). One of these f/2.8 lenses might cost a bit more, but second-hand hopefully will be affordable.

Even better for learning, but definitely more restrictive, would be a prime lens such as the Sigma 30mm f/1.4 or the Canon 28mm f/1.8 - or something similar. That way you can play with wider apertures -- at the expense of having no zoom capability. Image quality will be better.

I wouldn't spend money on a mediocre telephoto (55-200 etc.) lens at this stage. Get used to the gear and see if it's what you want. You might decide 17-50 is all the range your photography needs. You might decide you actually want much wider-angle shots. You might decide you really want to do some macro shots.
 
Regardless of the SLR camera platform you choose, you definitely want to pick up the vendor's 50mm f/1.8 lens. They cost about €100, are small & light, and give you maximum control over depth of field. If you choose a system that has a 35mm f/1.8 option (<apology in advance>HELLO CANON PLEASE WAKE UP</apology>) then that may be a better option as a first lens (though a bit more expensive).

The slow kit lens that comes with most entry-level DSLRs is usually of poor quality (the stabilized Canon model is probably the best one in terms of optics), but will be useful until you have a better idea of the kind of photography you're interested in.

BTW, by "slow" I mean "doesn't let in very much light"; such a lens requires slower shutter speeds as a result. There are a series of tutorials over at the Luminous Landscape that explain how all this stuff works.
 
After reading all these threads, I'm being swayed to get a DSLR. I found a Canon 20D for $200 -- body only. Is that a good price?
Oh yes, it is. It is a very solid body that is very capable. If you are looking for used Nikons, I recommend you have a look at the D70(s): it has very, very good metering.
I'm now concerned about lenses, they seem to be pretty expensive.
Regarding lenses, I think it's ok if you start with a kit lens and add a 50 mm lens. Both should be less than or around $100. If you want to spend just a bit more, get a Tamron 17-50 mm f/2.8: it's optically very good and mechanically still better than entry-level lenses.

You claim lenses are expensive: just think about the lens budget in a P&S -- even a decent one! They use lenses the size of cent pieces while it's not unusual that lenses for dslrs are the size of smaller saucers (think espresso cups) ;)
 
Hey everyone, thanks for the advice thus far. I went ahead and bought me a used canon 20D.

I do have a few more questions that I hoped could get answered:
1. Where do you buy your camera lenses?

2. member "HBOC" mentioned that I could pick up a used Canon EF 28- 105mm MKII for around $150. However, when I searched Amazon, I am seeing much more expensive prices. So I guess this ties in with my first question, is HBOC mistaken? or do I just not know where/how to look for lenses.

3. Could you recommend me a good/decent inexpensive lens for landscape photography.

Thanks again guys; I found this thread to be very helpful in my decision.
 
First of all, forget about Photoshop, it won't help you take better pictures. Good pictures need to be taken with your camera, they can't be made on a computer. (Even if you want to edit your photos on the computer, I would recommend you having a look at Aperture or Lightroom which will be a lot more useful to you than Photoshop.)

Regarding cameras, if you really want to learn the ropes of photography, forego any point and shoot. Get an old slr/dslr with a simple 50 mm/35 mm lens or kit lens. Only use the modes A, S, M (Nikon) or Tv, Av, M (Canon), i. e. avoid all automatic modes and picture modes. Experiment (= take a lot of photos). Even very old dslrs/slrs will do the job.

Once you know the mechanics of the camera, my advice is to `focus on the essentials,' i. e. think about what made you pull the trigger for that particular photo.

"DITTO" - 98% camera 2% photoshop, of that shot 90% is all about light the rest is composition
