Actually he is cheaper than AP a 10 slots 41 quarts rack at AP will cost $650 not including tubs (Tubs are $10 each another $100) and that type of rack must be shipped via freight I am in GA too and they quoted me over $150
C-Serpents can make you a 6 or 8 slots rack if that is the side you need and the tubs are also superior.
AP 6 tubs will run $390 + $26 (you do want those casters) + $75 + $60 in tubs = $551
If you are thinking about the economy 41 quarts from AP, I will advise against it (I made that mistake when I first started), it is cheap but it is very wobbly as well (the other economy racks are fine just not the 41 quarts).
A lot to take in consideration when you add rack price, shipping and having to spend more money on tubs, racks are not cheap but one way to look at it is how long they will last.
