The only reason I mention to lease:
Last year I had a leak. Workers came out to look at the tank. Noticed that the neck needed replacing. If I wasn't leasing it would have cost about $500 to fix.
Now, imagine if they had to dig out the tank or something similar for repairs.
I haven't really tired to calculate the cost/benefit breakdown, but I rather pay to have someone else worry about problems.
I have the tank only for the fireplace that is only run during the winter, obviously. So hardly used.
i agree with you. im kinda leaning to having just a regular above ground tank.
