Like everyone else said the prices are high but hes giving you good money for your trade, I would get the 153 if you are riding in both areas, you probably won't be climbing the steepest hills just starting out. Maybe look around a bit first. Call Arnie in St.Paul he has some 09 m8 std 153's with 5-8 miles for 6495.00 and these are clean, not sure if he has any left tho, great guy to deal with, his number is 651-261-5669, tell him Terry sent you. Hope it helps.
