Gramodels
Gramodels were one of the earliest producers of 1/76 resin models, and they are still going today. Originally done in polyester resin, but these days using polyurethane resin and some metal parts. As well as some 1/76 models they have made rather a reputation for 1/144, or N-Guage models which go well with model railways in the same scale. Nicely detailed and quite straightforward assemblies make into some neat models. Also in the smaller scale, check out their LCT IV as well!
There is just no substitute for visiting the real battlefields of WW2 in Europe if you have an opportunity to do so.
