Looking into a 29+ carbon frame to build up what will be a copy of a Trek Stache 29+ build. I've found this frame from a few vendors but this was the only one I found with purchase reviews:

Has anyone had experience with "Carbonbicycle Store" or does anyone know where else I could buy this frame from a more reputable retailer? I know Flyxii also sells it through their site. Would it be safer to order through them?

Thanks for any help.
