i really think delsalvo is a great value as far as framebuilders go. i don't think he's charging as much as he could for the work he's doing.
i haven't gotten a frame from him, but i visited his shop while in ashland for a UBI framebuilding class. he's a really nice guy who's pretty open to what the customer wants...steel/titanium, tig/lugs though he does mostly tig because people who buy his frames tend to want the really light frames.
he's putting S&S couplers on the frame i built at UBI. his NABHS show bike (Ti track frame w/ couplers) is now being ridden by one of the UBI employees.
