I actually bought 2 at the beginning of summer, when I first started throwing backhand. I'd been playing side-arm for 8 years, and figured I'd try out the disc innova touts as a beginner driver to practice the backhand. There's a nice review of it under the disc review section of this site. They're all 165, and come in a greyish white plastic. To be honest, I learned more from throwing the XD's I bought at around the same time than from the Ace, although I'm sure the Ace is just fine for beginners. You want something sensitive and slow to learn how to throw, not something that will cover up your mistakes. Definately not a rare disc.
