Eureka! Just FYI for anyone reading who may find this useful: Just spent some time on Bikepedia researching different model-year Kleins, as I found one I'm thinking of buying (Guy says it's an '01....but it's got the old-fashioned stem, which they stopped using after '98)....
Anywho....checking the available sizes for different years, I see that the Kleins are odd-number sized 98 and earlier...and even-numbered after 98.
So I'm looking at a 55cm....nice purple/green (blue) paint scheme...upgraded to Dura Ace.... $600 + shipping. Says it's near mint. Seems expensive to me....but it might be worth it, rather than spending months looking for a better deal. Had found a '96 in an ugly color (pink/purple/orange), kinda beat-up, and with the original 'Mano 600 components, for $425 shipped...so maybe this $600 deal ain't too bad?
If you trust the seller and indeed it is that clean $600.00 for a Quantum is a good deal. (I won't insult you with how much better I did on my 91.

) With Dura Ace it should also be a Quantum Pro, with threadless headset. But compared to my 2008 Jamis Ventura Aluminum my 91 is a much better bike, quill stem not withstanding.
Just my opinion but the early pre Trek Kleins and some of the Cannondales from that time are some of the best Aluminum bikes. There are some modern ones that come close but Gary Klein made a good bike that can be considered a classic. Look up Klein on Face Book and see how popular the Kleins are with their fans. Warning you will se a lot more MTBs but there are quite a few Road Bikes. And the old ones are getting harder to find, no I am not selling mine..
