I just got the Nashbar 29er SS for $375 shipped on-sale last week. Other than the brakes needing a little time to set up compared to BB7s, it has pleasantly surprised me.

I had plans to use it as a winter commuter here in MN, but I am hitting the trails this weekend with it completely stock, as it shipped. I may change the rear cog to a 19 or 20 tooth depending on the terrain though.

Oh, and it is an aluminum frame.
