As stated above, RMR and Jimmy Flintstone offer these in resin as well as the Danbury diecast version. In the past, resin cabs were also offered by Rick Manz and Ron Cash, though both were quite a while ago, but they still show up on eBay once in a while. All are very slightly different, and Manz also offered a sleeper version. The Cash version was excellent, the Manz version less so.
