Although $35 is a bit steep i agree that its a very nice shirt. I got one here at the massachusetts show and its actually normally sized rather than the often shapeless shirts you find at some concerts and its very comfortable. Yeah, its a lot of money for a t-shirt, but the opportunity doesn't come up that often so if you're gonna get some wear out of it I don't think its all that bad a deal.
then again, you can find some interesting bootleg ones too i'm sure, a guy in the parking lot at my show was selling a nice one but he didn't have anything left in my size. Too bad though, they were only 10 bucks :)
