My last two purchases have come from Cycletrader Online. I bought a WR250F in Ohio Friday, and I live in Alabama.
Cycletrader basic ads are free. The local Alabama/Georgia Trader charges $59 for a print ad with pic, and the ad runs until the bike sells. Your print ad purchase includes a deluxe online ad with pic as well.
I've never tried to sell or buy a TM, so your mileage may vary.
used to be free on cycletrader, now im pretty sure they charge $15 even for a basic ad. i did manage to get my CR on there for about a week before they changed it.
