What about the track frames? I've tried doing some research on the Miyata Track Frame (Miyata Pista?) and can't find any real good info on them, I found one online for $400 and started to talk to the seller, I like the frame, looks good, I heard that the tubing they use is pretty good, Double Butted Cromo tubing i think? I haven't heard anything bad about them thats for sure, but idk if its a good pick up
