Well dude, if you're in the 559 (as I am), then it's not quite so easy as 'I live in Cali'. I have FB racks and they are not easy to keep warm in the winter. Humidity is always a problem. As to calling up FB, since they are just up the road in Turlock, it shouldn't be too hard to get ahold of them. As to cost, since the last time I checked, CB70's were in the 1k range for a 10 tub rack system, I don't see how you're doing the math on that one.

Good luck with your project.
