I've never bought anything from them but have friends who go there as first choice and have had no problems and will certainly continue to use them because of their great focus on more unusual stuff that you likely won't get anywhere else.
I can't get past that from what I can see, they charge top dollar for everything they sell, especially pricing on used instruments which does seem to be 'all the money'.
Good luck to them and I hope they continue to do well, but for that reason I'm out.
