I really enjoy this product as well!
What an awesome idea. Initially hard to find, the Activision version is easier to get (Radio Shack) but the controller leaves a lot to be desired.
Got Atari 10 in 1 on ebay for around $20 AFTER shipping.
Only downfall was paddle games...I'm really not that bad at PONG! And the "english" lacks a little with the joystick! I do hope the quality of the internal parts is better than the old days. Remember having to buy replacement parts and do home repairs??!!
