I disagree that HD is not ready yet for the consumer. Sure, you COULD put off your purchase for years unit all the dust of 720p vs 1080i vs 1080p / Blu-ray vs HD-DVD / etc settles, or you could buy an HDTV now and enjoy it and how it can improve your video experience with current technology.
I own a 42" Sony RP-LCD HDTV that I purchased about 6 months ago, and have been astounded at how great the majority of my content looks on it. This set is only 720p, and is being fed progressive scan DVD (no upscaling), QAM HDTV local channels, and various DiVX/XViD files played off my iBook. I'm very happy with the purchase. The ONLY thing that looks subpar on this set are lower quality XViD's, which also happen to look crummy on my old SDTV.
You really should read around
AVSForum.com and get an idea of exactly what is out there. AVS is the definitive community for HDTV advice, IMO.
As far as recommendations go, I will suggest that you look towards LCD instead of Plasma if you need a flat panel. If you don't, check out SXRD, RP-LCD, and DLP sets. Stay away from cheap brands, as they often have lower quality scalers, which will make your non-HD content look poor. When you think you've found a model you want, read everything you possibly can about it over at AVS.
Personally, I like Sharp Aquos and Sony Bravia's for LCD, Pioneer and Panasonic for Plasma, and Sony for RP-LCD and SXRD. I won't use DLP's due to the rainbow effect that my girlfriend sees on them. These are just personal preferences, and I again suggest you go read AVS, as well as take a trip to your local store and watch the sets. Many stores will also let you bring in and hook up your TiVo so you can see how your exact content will look. Everyone is different, and no one can tell you what your eyes will find to be the best picture but you.
