Well the weapons and uniforms of the SS are cool and I think people worry about not being up to standard to represent well-respected units like the Rangers etc. Those Units do exist though. When I joined up my choices were American Infantry, German SS, German Weer, or Scottish Airborne. The Scots were some damn cool guys. In fact I was considering putting together two kits, But that stuff gets expensive! The basic uniform for the Germans is the cheapest I believe, which was a major factor in my choice. I think I probably spent close to $1000 and I just had a K98 bolt-action rifle. Some of the guys who are into it spend thousands on automatic weapons and vehicles.
We, the 10 SS, had 3 BMW motorcycles with sidecars, a kublewagon, a 2 1/2 ton truck, and a towed anti tank gun as well as several MP-40s and a couple crew served machine guns.
