Good quality and nicely made, but much more conventional in design than BF. Essentially, a well built and finished (and quite heavy) conventional box, without the extensive bracing/sophisticated porting BF uses. I had a 2x12 built by them, to which I added my own drivers (I don't know whether it's still the case, but Zilla used to build cabs for you to fit your own drivers). You really need to try/compare them (which is obviously more difficult with custom-built cabs, which tend not to be sold through retailers, so you can't walk into any shop and do that). Hope this is of some help.
