Hi
1.QUANTITY
First off, the memory card the camera comes can usually hold only a couple of pictures, so you'll need to get a new memory card. A prosumer 5MP camera (like the Olympus C-50) has their highest quality TIFF pics to be around 15MB, so if you want 40-50 pics, you probably need a 512 MB memory card. The highest capacity memory card is 1GB i think.
I must say tho' that these ultra high quality pictures can be overkill, so a really high quality pic will actually be around 5-10MB.
There are many memory card types, compact flash, secure digital, xD, memory stick. Not many of these are compatible with each other.
2. QUALITY
A good 4x6 print requires at least a 2 MP (megapixel) camera, I'd recommend getting at least a 3MP. For page size prints, get a 4+MP camera. I'd say quality is becoming comparable to film cameras. You'll get good quality with today's digicams.
Printing your pictures yourself with a photo printer is the most convienent, but the quality isn't quite there yet. Also it costs a bit more if you factor in the printer, ink and paper. The advantage is that you get the prints immediately in the privacy of your own home. I'd say the cost for a 4x6 is over a dollar at least.
For online printing I recommend Ofoto by Kodak, its from a reliable company, and the pics that come out are high quality, no matter what resolution camera, no matter what size. The price for a 4x6 is $0.49 I think for Ofoto. Other online companies may be a bit cheaper. A disadvantage of this is that you should have a fast internet connection (ie cable) to upload the pics to the website, but an advantage is that you can put your album online so friends and family can see the pictures and order prints for themselves.
The same price follows for local print shops. Walmart for example will print digital pictures for $0.49 per 4x6...just drop off your memory card, just like you would drop off film. An advantage of this is you can get your pictures the day after or sooner.
3. ZOOM
Most point and shoot cameras have either a 2x or 3x zoom, plus some digital zoom. The digital zoom they advertise isn't true zoom...they just blow up an area of the picture and fill in the spaces. You might be better off blowing up the picture in a picture editing program. If you're going professional, then there is a wider range of zoom available. Otherwise most of the cameras have 2 or 3x optical zoom, which IMO, is not bad. I'd always want more though.
4. COST
You'd might be better off doing a google search and comparing prices, but a good 2 MP camera will be around $200 or more, 3 MP will cost around 300 to 400 dollars, and so on. I'd say if you're looking for a good camera, be prepared to spend at least a couple hundred...but there are cheaper cameras out there
5. BRAND
Can't go wrong with Canon, Olympus, Minolta, Nikon, Fujifilm, ...anyway I'm not much help there. I'm sure someone has a horror story with some manufacture tho'
Hope this was helpful.
