Not to rip on BG, but I notice that his prices have gone up considerably over the last year or so (understandably). The standard BLT is now $2350 sans shipping and assembly. Compare the BLT with the Surly LHT which costs around $1100 fully assembled at your LBS: The BLT is better, but is it worth more than twice as much? The LHT would need to have the crank changed to smaller chainrings, but other than that the components are as good/reliable or nearly as good as the BLT.
Even after paying extra to replace the cranks the LHT is still costs about half as much. The BLT & RNR look like great bikes, but I do think there are better values out there.
