First of, cool to see a fellow Austinite

. If you do get it, post good pics, and I'll hope to see you around town on that ride.
I would probably try to talk him down a little - for some odd reason, the market for nice bikes over $500 seems to have really slowed recently - but if he won't budge, that's a reasonable price too for a near-NOS condition US MASI.
EDIT :: out of curiosity, which one's yours?
