DO check your fill place first! Many scuba & paintball shops will not give you a FULL fill, some will.
"I" NEVER had any fire dept. lick but was in larger city's. In A small town of 2,000 in TN I could have gotten the volunteer fire dept to fill.
Find out ahead of time.
I went with a 45minCF tank w/fill set up and only 12 1/2 years left for $300.00 delivered ( different dealer than you mention).
I also went with the ^630.00 Altros Boost si am free from any shops, As we must change to snow tires in the winter and chains sometimes - keep spare wheels/tires around- the little misses was HAPPY to buy a shop compressor, " and change tires like they do at the tire shop?" .
Keep us posted.
