Here are plans to build your own drag sled. If you take these drawings to a local machine shop or sheet metal shop they should be able to build it from scrap for very little money. The biggest cost will probably be getting it powder coated (which I Highly Recomend). I have the files hosted on Anywhere, so if the link doesn’t work PM me. I’ll also e-mail the drawings to anyone who wants them that way, just PM me with your addy.
