I have purchased a bunch of these at surplus sales on a couple local military bases. I fixed them up and sold
them. Some after using them myself before I decided to buy my new Scamp
. Made a nice profit too.
Part of the problem is that the rental people just didn't do nearly as much proper upkeep and repair. They aren't that hard to maintain if you bother to try. It's often a local sealed bid sale so it might be worth checking with them so see if they have any they are planning on selling.
When they are sold
on this site the bidding can get pretty wild. We'll see.
