Hey, im glad you were able to score some tanks!! I'm sorry i couldnt help, but it looks like this ended up being a much better deal. I cant wait to see what you come up with. Keep us all posted!! My build is on the back burner for a few months. I got busy all of a sudden, and dont have the free time necessary. GOOD LUCK!! ...and yes-the oil in those pigs will leave a nice smell for quite a while. I suggest pouring in several pounds of t.s.p. and letting it soak for a while before you purge them.
