I recently finished my third Grot Tank. I found these great World War Toon Tanks from MENG Models. I started with the Sherman Tanks however I have 4 other model kits sitting on my desk. The company currently has 6 different tank models out and they make for great conversions. I will be getting to work on the rest of the models after I finish a few other projects. The cost of the models differ depending on what model you purchase. If you are looking for a fun project I suggest taking a look at these models.
