MINDGAME is right; stay away from RCA.
One good thing the RCA set has, though, is DVI input that supports HDCP. If you're planning on using your set for HDTV, you'll likely end up needing an HDCP-capable DVI port in the near future. Also, HD-DVD will likely use DVI as well.
IMO, if you're planning to play videogames on the set, stick with a direct-view set (like the Samsung mentioned earlier), or move up to an LCD or DLP based model. The direct-view won't be as easily affected by burn-in as a CRT-based projection or plasma set, and LCD and DLP technologies aren't affected at all. The LCD and DLP options will be waaaaay more than you want to spend, though.
