Buckmark, Ruger or even the S&W or Taurus revolvers are all good choices. I have the first 2 and wish I had the other 2.
I remember listening to Dark Side when it first came out. There's as slightly different quality to sound from vinyl that you don't get from CD, but each has it's merits.
I saw Tull 10 years ago in Vegas and ELP the same weekend. If I could only see one, I'd pick Tull.
Remember, OT doesn't have to mean vulgar or in poor taste.
