I keep looking for a cheap moped in my area and not finding it. The other day I found a 2-stroke 100cc motorcycle on Ebay, practically in my backyard, 1974 with 1087 miles on it, and currently going for $200. It needs a few parts and repairs, but I fully intend to be among the last-second bidding frenzy unles the price climbs up a couple hundred more in the next two days. :P
There seem to be more mopeds around lately, though. They are being hauled out of attics, garages and sheds, it seems. Yesterday I was driving through town and saw someone on a ped a few cars in front of me. Traffic was too bad to get a closer look, though. In the evening I ran by a farm where I had seen someone getting a moped out of the barn the day before (and another staying in the barn) and saw a kid out on the lawn fixing up yet a third bike, a Honda Hobbit. I stopped and chatted, and the kid says they collect mopeds and he fixes them up, some to keep and some to sell. So, at least I have my eye on a possible seller (or source of cheap repair labor!) :P
