regarding the IMS tank earlier. It's confirmed indeed it was an IMS tank. The seller wants me to mail him a cashier check first. he ships it, then i will send him a second check to cover the shipping cost. I've done paypal, but never done cashier check before. Plus he gave me an po box address. to be honest, I am skeptical now as he was when I called him stating I am from a different state. This deal probably save me about 70 dollars than buying new from justgastank. Worth taking the chance? I still like the acerbis tank better.
