I paid $2500.00, out the door, for my Q5 w/barts. If I'd had cash money I probably could've gotten it a few hundred cheaper. Who the heck has $2000 + in cash on hand, though.
You can find stuff on ebay for for $600 or $700 cheaper, but when I'm spending $2000+ on a bass, I wanna be able to play the thing first AND have the option of returning it if I'm not totally happy the next day. With Ebay you don't get that luxury. Also, I had in my mind exactly what I wanted. Q5, Bubinga top, Barts w/ preamp. I watched Ebay for a long time and never did see the exact bass I wanted ever come up for auction. Once again, with that much money involved, I was not willing to seattle for just anything. It had to be exactly what I wanted.
YMMV.
