I had never heard of them. I checked their site. They don't carry a lot of vintage drums if that would affect your decision. They did have a very nice looking Ludwig Pioneer in gold sparkle for $369. They note there is no sales tax collected in MA. Not sure what that would be about because MA certainly has a sales tax and it isn't low (6.25).

Does seem mostly to be geared to guitar related items or new drums. Didn't check what the fees might be.
