Welcome aboard, Craigster.
I'd trust this forum's "Marketplace" section before treading into eBay waters... too much craziness on eBay for me to plunk that kind of money down. The folks here on Marketplace are 99.99% straight-up, from what I've seen and heard. That's not to say that everyone on eBay is a crook, but that's a good amount of money to chance.
Plenty of good info here on the forum... take what you need, share what you can.
