Anything a little more unique? I'm perfectly willing to buy used (but not abused) if it's something that ought to be reasonably available in a ~56cm size.
These bikes all look good quality, but none do any more for me than my trek already does..
What's it cost for something with WOW factor?

[edit]
Alien might be getting a little closer- do they just offer that one frame?
Weighs more than an IRO, though- assuming IRO includes the fork weight.
