Lefty,
I would advise you to go check out the excellent forum on the matter: www.avsforum.com In my opinion it's the #1 site for information on the subject of widescreen/HDTV. Another excellent site is: hometheaterspot.com. These 2 sources should be able to answer all of your questions.
Spend some time in these sites and you should be able to pick up the information you need to make an informed choice.
I was recently in the same position as yourself. The first thing that I would advise you to do before investing in any HDTV is determine what digital channels are available in your area. If you are in a major market you should be OK and might possibly be able to get all your major networks digital stations. This will first help you to determine if you can get HDTV. The only real reasons to get a widescreen are you want HDTV or the majority of DVD's you watch are in an aspect ratio other than 4:3, right?
Ok, so once you decide if you can get HDTV and you still want a widescreen your next choice which be which manufacturer. Some things to keep in mind. Right now you are faced with purchasing both a Television and a set-top/HDTV/Satellite receiver. All the major manufacturers set top/HDTV box's are also Direct-TV satellite receivers. A subscription to Direct TV will also be a good idea as it will at least allow you to receive HBO High Def channel, and the HDNET (new high def channel). Add this to whatever digital locals you are able to receive and you will have a nice choice of HDTV programming.
Oh yeah, you are going to need an antenna mounted on your roof. Some have had success with indoor rabbit types but the optimum choice will most likely be a roof/mast mount UHF antenna. Again this will depend on whats available in you area.
This brings us to the TV itself. I have seen the Louwe televisions, they are nice but expensive. Kind of like the Bang and Olufson. I think you are paying extra bucks for a fancy looking tv. But don't take my advice read what others have stated in the forums I mention above.
Right now the major players, SOny, Toshiba, and Mitsubishi all offer very nice rear-projection televisions that make HDTV look just superb. A smaller size 40" you can pick up for around 1500.00 new from authorized dealer. You can go bigger and spend more.
The television I choose was the 40" wide toshiba 40H80. I just love it and would recommend to others. The new model is the 42H81. This is also supposed to be superb, but go see for yourself.
The majority of reviewers recommend using the same manufactures set - top bot Toshiba/Toshiba, Sony/Sony. This will avoid any compatibility issues and is also encouraged by myself. I went with the Toshiba DST3000. This receiver pulls in all my local digital stations here in the bay area, perfectly.
I use the channel master 4 bay bowtie which costs about 25 bucks from Stark Electronics. I think it cost another 25 to ship it. I got all my antenna accessories for cheap at radio shack. This is one area they still reign supreme.
Next time you go into good guys, ask em if they have any UHF antennas for HDTV, They will either say, Huh??? or try to sell you a 500.00 Terk that you don't want or need.
I think at this stage in the HDTV game, I wouldn't believe a thing you hear from the mass market guys. DO your research on the sites I've suggested and I think you will be able to find your way to HDTV bliss.
Good luck
