Here is an electric one. They have a few different models. That would work for you. They have the prices when you look under the tab F.A.Q. They seem to run around $65-$133 with shipping included. They have ones you can mount and then ones you hook up to the hitch ball. Click Here
Okay, I have been researching these units for two to three weeks. I went to several sites, (Listed below) and talked to several salemen. I have settled on Power Mover. (www.powermoverinc.net) They are selling me their higher end model for a lower end price... $625.00 vs $839.00. very excited and will post my review of its use when it arrives..<br /><br />Other sites: www.powercaster.com
