I have two of the Offensive Miniatures ones, they are all metal but are easy to put together. They also come with a crew, guns and extras like stowage, sand channels, etc. I reviewed them for WI Online but it isn't up there yet. Scale wise, they are a good match for the Perry plastic 8th Army but would also be ok for larger figures. I like my two Chevy's and would recommend them. £20 each and just glue and paint for the whole package.
