I am curious as to opinions regarding VS, Marui, and Hen Long Tanks. VS offers a comparison chart which challenges the quality of the others. Is VS really a better quality? Is Hen Long prone to a multitude of problems? I was considering on getting the "Snow Leopard."

I would also be curious to know if anyone has information on replacement tracks for marui tanks (not rubber treads). Sadly when I purchased my Marui tanks a couple of years ago, I neglected to get the plastic piece together tracks.

Finally, are there any US locations that carry airsoft VS tanks?

Thanks
