The image quality does look nice. I've been impressed with some of the Ataris I've had recently...but some have more RF interference and/or washed out color. Not sure if it's the generation/revision or just the age (capacitors, etc).

Note that these adapters won't do anything that the old switch boxes don't do...it just takes out the switch, which often goes bad, and it keeps you from having to get one of those 300 ohm to 75 ohm adapters to work with your "cable ready" TV.

I can't imagine how a "counterfit" RCA to Coaxial adapter would make a difference....or even make sense.

Lastly, you get them at Radio Shack for liek $3.39, so you really don't have to buy them from AtariAge, eBay, etc. I just bought 4 or 5 the other day to include with the 2600s I need to sell :-)
