I have a Ludwig Black Magic 6.5x14 (which is probably the same drum as the Pork Pie BoB with a different badge) and it is a great drum. There's just...something about the tone and feel of an actual Black Beauty that sets it apart from the seamed-shell knock offs but I'm completely satisfied with the Black Magic and I'm even more satisfied with the money I saved.FWIW, I put a BB and Pork Pie BOB side by side with the same heads and tuning and was able to get the BOB to sound about 90-95% like a BB. Needless to say, I ended up buying the BOB. But, I'll definitely pick up a BB one of these days. It just has that extra bit of sweet, rounded tone that is missing from the others.
Bottom line: if money is an issue, get a BOB to tide you over and save up for a BB. You'll at least be able to take the BOB out to gigs and beat the hell out of it until then.
