C.Itoh was the alternate name for Bridgestones, but according to Sheldon they're 'pretty crappy bikes'. The motobecane might be nice, but french threading can make things difficult (although velo orange is going to be coming out with a sealed french-thread BB, so that would make things much better) - finding stems and headset parts could be painful though. Le Tours are unremarkable but solid bikes and probably the safest bet.
