believe it or not, you can get a nice computer game at "Toys R us" i got one years ago for 25 bucks. an Excalibur. small but competitive!
Computerized chess sets

If you want a tournament sized board and pieces it would be hard to be the Excalibur Grandmaster set if you can find a good price for it. Most places on the internet say it plays at Class A USCF. You can find stronger computers but very few are tournament sized as well as being auto sensory.

I still can't understand why some manufacturer doesn't start making inexpensive chess boards that can communicate with a PC, or at least upload games to the PC. It doesn't even need much of a brain - we all have computers that play great chess; all we need is a physical board that hooks up to it without the DGT prices. I know you can make your own but I'm not talented in that way. It seems like it would be easy to make one for $20 and sell it for $100. I really don't understand why no one does it.
I am looking for a computerized chess set. One that you can adjust the level of dificulty. I am looking also for a good price. Would i find it on ebay or amazon?
