A few years ago, AMCDave told us about the re-release of the old Revell snap kit
Revell Combat Crushers Quake Sherman Tank Plastic Model Kit
They were pretty cheap at the time, but are accurate 1/48 scale models. Not a lot of detail, but easy to build and look really good when painted properly. Maybe someone has a stash of them, or maybe they will be re-re-released again.
