I own the original Classics figures that were released in retail stores and skipped the repaints from previous lines. I also never attended the shows and conventions so I don't have any of the show specific figures. As for current and future purchases of 2.0, I bought Prowl, Sunstreaker and Tankor the other day and will be picking up Onslaught and Silverbolt when they're released. I'm still on the fence about Powerglide. He's an original mold, which I like, but I don't really dig his look very much. As for Wave 3, I'm going to be picking up Sideswipe and Silverstreak. I don't think I'll be picking up Ironhide though - he's essentially a repaint of a Movie figure right? What's your Classics collections like?
