http://reverb.com/?query=henretta&utm_source=gearmandude Reverb is THE buying and selling source for all things new/used/vintage guitar and bass gear related...there's also drum and keyboard and other stuff! A large percentage of listings are in the 'make an offer' form, so you can really score some great deals. Much lower seller fees than eBay, and it's focused on music gear exclusively, so you don't have to wade through vintage Ford Mustang fenders and headlights, when you're really looking for a '69 reissue Mustang guitar. The selling format and layout is WAY faster and simpler than ebay as well. Check it out!
