Yes.
The quality and service are top notch. I have an 8-level FB- 27x33x8 rack with the 11" heat panels. As Mookfu mentioned, it is literally bulletproof.
I've used Boaphile and RBI racks, and while they are nice, I don't think that you can compare them to an ARS or FB setup in terms of durability.
Plus, as you downsize, you can sell of levels of the rack.
