The NeXX Carbon offroad is very enticing, and at $450, it's one of the cheaper full carbon options. I'm quite smitten with the Shoei RF-SR which is, apparently, the new replacement for the Qwest (which was a great helmet, if a little large in the shell - I'm assuming they're retiring it in full embarrassment of the stupid spelling of the name).
Anyway, I have a barely-used, in-great-shape GMax GM54S modular helmet that I absolutely love that I'll ship out for $100 to anyone interested here in the CON US 48. Size Large, pearl-white color. Has the integrated rear-facing light with three modes, drop-down sun visor, normal d-ring retainer.
