That is the VERY first thing I thought!
Why is everyone talking picture quality?
This member has a TV that accepts 480i video only. He shouldn't be talking about upconverting players, but simply a cheap reliable player.
At the end of the day, I'm hard pressed to wonder why he wouldn't get a $20 Coby player or something similar when the most he can hope for is 480i.
This is what you should get:

It's inexpensive, from a quality manufacturer, and provides all that your TV needs. If you want upconverting because the kids are about to move out and you will buy HD very soon, then get a HD player now in Blu-ray and enjoy the improvements you will get now, as subtle as they will be - remembering that Blu-ray players have no issues playing your DVDs as well.
