www.music123.com are great. I have had good experiences with zzsounds.com also.

www.8thstreet.com will give you a good price though there customer service sucks.

www.musiciansfriend.com are just money grabbing bastards. It will be a long time before I do a lot of business with them again !!

eBay can be hit or miss. I think you kneed to know what you are doing to get a bargain. I have had some excellent deals and let some really great bargains go however I know of plenty of people who have had their fingers burnt !
