Prices ( and life as a whole ) are diffrent on this side of the pond. And much to my astonishment a White SG Bass without OHSC was sold for GBP 795 on evilBay yesterday ....
That was BIN from a shop, though, with a warranty. For a private sale, 675 isn't a great bargain, unless white is worth 200 quid.
The guy that runs the guitars.co.uk site used to have a shop with a very successful internet guitar business attached. Then it disappeared. Now he's doing this. I can't quite work out what it is, seems to be just private ads and a gateway to other shops.
