I'm located in California, so they're definitely available in the USA. I also have 2 Ridgid (peddinghaus) vises which are very similar, come with the same non replaceable jaws, but Ridgid does give them a lifetime warranty, and says they'll replace them if you ever break the jaws. Hopefully I never find out about that.
The hard part has been locating accessories for this FZA vise. I contacted Gedore (the re-brander) about purchasing the option pipe jaws for it. After they did some back and forth with the German home base, they're specially shipping out and selling me a pair at double the price if I was in the EU (50 bucks). Theres also a swivel base available but finding it in the 150mm size, the price was like 140 euros + 40 euros to ship it. I've already got 2 swivel based vises that I never swivel ever. So this vise can stay stationary.
The only small let down of the FZA vise has been that they didn't stamp it "Made in Italy", though it seems clear from all documentation provided by FZA that it is.
