Left to Right:
Gerbirgsjager from Warm Acres (to get an idea of scale)
Bolt Action FJ Officer
Black Tree Design FJ with MP40
Offensive Miniatures officer with STU44
To me, they all scale up nicely and I have some Artizan and Crusader in my Herr army as well (too lazy to pull them right now to take a photo), but they line of fairly well in size for the most part. Once you mix them up and paint them you can hardly tell the difference.
I can say that all four of the retailers above are top notch. Black Tree Design is great if you want to save money, the quality isn't as high but for your money you get a damm good deal. Offensive is slightly more expensive but they have some nice detail and I do plan to order more later. Warlord does a good job with thier Bolt Action Line, I picked up a few figures to test their line out including a few FG42s, officers, Medic, Sniper and Flamethrower for my FJ. Hope this helps.
