Seeing that it's been over 20 years since I've seen them live and now I'll be seeing them in Houston, I was just wondering what kind of merchandise can you find at the venue? I know they will have event t-shirts, but I'm especially interested in signed items like 8x10's, CDs, or drum heads... Also, do they still offer tourbooks as well??? And, lastly, are prices resasonable? Any help is greatly appreciated! Thanks!
