Best place to get an Atari 7800? Anyone have a spare?

Ok, Groovybee has harrassed me into getting a 7800. I have never owned or even played a 7800 and its 2013!  Shame on me!

Anyone here have a nice priced one? What about a trade?  I have plenty of spare Intellivision consoles and some common games like a starter kit for a newcomer to Intellivision. You guys know Groovybee is going to make Intellivision games one day?

Anyway, what is an average price for a nice working un-boxed console?

Any help is appriciated.

thanks
