These are pretty damn good. Go here to see what is available. Bought these from Frome Model Centre. If you don't have a model shop try Ebay. Most of the range is German and Soviet but they do some British products. They fit together really nicely and they cost under a fiver for most of the models. So can you game with them? There is quite a bit of stuff available for 15mm which is compatible - the Plastic Soldier company has a range of 15mm vehicles and figures. In metal and resin there's Peter Pig.
