Of the choices you gave in the link, I would recommend the RCA. I don't have any HD RCA TVs, but I do have an RCA SDTV that is very good. Also, I have never heard of any of the other brands of TVs, and since I recently went searching for TVs less than two months ago, I think it's better that you go with the RCA.
If you're not looking to purchase the TV right now, I would recommend saving a little more money and purchasing a Vizio. I recently purchased one (thanks to someone on these forums alerting me to a great sale!) and I have to say it is fantastic for gaming.
Vizios are a great value, and purchasing a Samsung or Sony seems silly because you'll only pay more for the high-profile name brand. The television I got was a 32" Vizio, and it cost around $500, with tax included. I know you set your price range at $300-350, but if you can manage to get a little more money together, you can stop looking at entry-level HDTVs (most of which only produce 720p highest resolution) and begin looking to mid-level HDTVs (most of which are really great deals).
Just a few tips:
1. 480, 720, and 1080 correspond to the amount of lines of resolution that a TV uses. Obviously 1080 is the highest-definition resolution, but unfortunately, most entry-level HDTVs do not output up to 1080, but rather to 720.
2. If you're going to be playing games online, you'll want to pay attention to the Response Time of the TV as well, because sometimes TVs will have a delay between when you do something and when it appears on the TV. LCDs in the past haven't been good with Response Time, but they are becoming better and better. The TV I got has a response time of 6 milliseconds, and there is no visual lag when I play Halo 3 or Call of Duty online, and works great.
Those were the two things I was concerned about the most when I made my HDTV purchase, and the Vizio was also a great value, as I was expecting to spend ~$700 for a TV like that, but only spent $500 (which was exactly how much I wanted to spend). If you're planning on purchasing from Wal-Mart, take a look at the Vizios that they have in-store, as they, along with Target (where I got mine), are some of the only stores that sell Vizios. I was originally planning on purchasing from Best Buy, but unfortunately BB does not carry Vizios, but the deal was too good to pass up!
Here's a link to
Vizio's products page, in case you're interested. But as I said earlier, if it were my decision, I would purchase the RCA out of the choices you gave. But I agree with this:

The way I see it, if you're going to drop some money on a HDTV, you might as well get something worthwhile and reliable.
Funny how this thread was started about a decision to purchase a LCD HDTV for around $300 and it leads into a discussion about $8000 Plasma TVs and motorcycles!

Beware: M$ may spend more $$$ on lawyers than on their products.
