I second HntnFsh completely. Love the Yamaha T9.9. No idea why they don't make the 8 anymore but that ship has sailed so the 9.9 it is. Had mine for 6 years and never a hiccup. Easy to do the maintenance yourself and save a bunch as well.
Leads on price when buying new is going to be tough. Pretty standard on what they are worth. May find a winter time sale, last year model or something along those lines. I'm a huge fan of Northwest Marine and Sport in Pasco, WA. I save a bunch by making the drive to buy a new boat from them. Straight forward sale, no screwing around when I showed up, water test and out the door. I don't know that the savings would be there on a single 9.9 kicker but might be worth the phone call to see if they want to move a motor.
