Their M60s are not complicated at all. In my opinion, they are best M60 kits on the market. I built their USMC M60A1 w/Dozer Blade and have their M60A3 kit. As far as I can tell, their M60s have a rubber track that is quite nice that connects with a metal rod. I had no issues with them at all. Well detailed and easy to assemble.
Here is my USMC M60A1 w/Dozer Blade.

I also used their CM-11 hull on an M60 AVLB conversion.
