I've bought several things through audiogon. Never had an issue at all. Audiogon is mostly high end hi-fi equipment, and as you likely know, people who buy this kind of stuff generally treat it better than their childrend. They also usually suffer from hardcore upgraditus, so great stuff pops up on there all the time. I've bought all my Rotel gear from that site.

Good luck. Let us know what you finally end up with.
