I've been toying with the idea of several XC frames, and I'm on the verge of purchasing one, however before I do I figured I'd toss up a thread to see what kind of ideas I can get generated here. In this instance, I know what XC frame I'd go for, but I'd like to compare it to an AM (6" ish) travel frame to further pick them apart and see what I want to do.

Budget is kind of slim for something like this. I'm hoping to spend no more than 600. I can make this happen with the XC option, but I'm not too sure about an AM option. Are there any frames out there you guys suggest with about 6" of rear travel fitting that price range?

I would save a bit longer so there's no price compromise: Yeti 575 or and ASR-7.

Ehh, a quick google shopping check of those frames reveal it's a bit higher up there than what I wanted to spend. But eh, I'll still consider it. What vendors do you suggest I look at? All I'm bringing up is used ones.
