So far as I know DeRosa has kept control of his name; unlike Masi which are now generic bikes though, from what I hear, a good value. Because of that DeRosas, like Colnagos tend to be highly valued and expensive though the collectors are after the vintage steel frames.
I wouldnt consider Masi's to be "generic", you can find some nice ones for a good amount of $$$, just saying. No disrespect, but you make them come off as GMC type bikes, when they're really not. Probably a good entry level road racing bike maybe?
