$4K for an AYA boxlock? You can get a lot of nicer things on the market for that money, new and used. If it is important, you are unlikely to get even half your money back if you decide to sell it. If you want a box lock, get a Uggi and save half your money, or look at the new Fausti's. If you want reliable, get a used BSS or SKB, or look at the NEW SKB's.
