Hmmm... interesting levers! Never seen them before.
My STI'd roadbike is a 1989 Paramount OS3 actually. It was all used parts I got redicuously cheap, so total including I the bike I have about $320 into it. Well worth it from my standpoint but not everyone can build a bike or get parts hook ups like someone that works for a shop. If he likes the bike enough to drop the coin then do it by all means.
