I've only ever gone thru Sweetwater for online purchases (how I got my jaguar, but it took forever). I've heard good things about ordering thru Musician's friend tho. Lots of people say that they're very good with going lower on the price if you want it. Might try them out at some point.
Never had a problem with them either. They've always given the discount or cut me a deal if I called for it. Only downside is that I have to pay tax since I'm in CA...which makes those 15% off discounts a lot less awesome
