My son and I each have a Scrambler and for the type of riding we do, they suit us fine.
You can get the frameset from them for 139 shipped and get the rest of the components for cheap it you look around eBay and CL.

But if you're going to spend $650 there are much better options out there for you. Just use google.

If you're just going to have it for college commuting I would check out bikesdirect.com They have FG/SS bikes at a decent entry level price.
