Careful with it, don't forget most of those are double-walled. I've heard of people cleaning em out good, maybe even filling with water before cutting, then use a torch to cut a hole in it----BOOM!!! It only takes a real small leak in the inner wall.......
I'll admit tho, I've thought of getting one for a roller.
AND, $101 ain't much money for that size tank! Congrats!
