Although I'm leaving DP discussions (*waits for the inevitable horrahs), I'll still be around the B&S board from time-to-time. So...
I've got an UNTESTED (I don't have another Atari, or any hookups) Atari 2600 Junior model *deck only*. It's in decent shape cosmetically, and I was told that it works when I bought it with some other stuff. There is a rattle inside the system, though.
So if you're willing to take the chance of it not working (although I think it will...), shoot me an offer...
...or...I might very well trade for complete U.S. Dreamcast games in nice shape.
And as for references, I have several here on DP, and I'm an eBay Powerseller with 100% positive feedback out of 281 .
