INTV versions, which is most reliable?

[Zaxxon]

I see a lot of different looking versions. Are they just cosmetic differences or are there ones that are more reliable than others? I've had a few of the 1st brown-gold version that were flaky or appeared to be dead/fried. Is there any fix for these dead ones I always seem to find or does the CPU just overheat and cook itself?

Personally, I swear by the Sears Tele-Games Super Video Arcade models. They're the only INTV model I've never had a problem with.

I prefer the INTV III myself
