I suggest a hose end removal tool from as well. Also, if you want to do any work on those damn Apeks first stages, you will need the special spanner wrench to remove the diaphragm cap. I tried strap wrenches, vise grips and other modified common tools and ended up wrecking one of my diaphragm caps. Why they would design something like that that needs a special tool is beyond me. The parts kits for those regs are outrageously expensive and very hard to find too.

Probably one more thing that you might want someday is some replacement gold plated terminals for inside the O2 cell connectors. The wires are really fragile and they can break. In a pinch, you could solder another gold plated connector on, but if you want to do it right, there is a very special crimp tool you can buy that crimps both the wire and insulation at the same time. Extra crimp terminals only cost a few cents each, but the crimp tool costs like $140. However, there is no other tool that will substitute. If you want, I can tell you where to get that tool and some extra terminals direct from an electronics supply house. This is the kind of thing that could screw a dive trip potentially if you don't have one. I admit though, I haven't yet shelled out the cash for one, but I'm sure I will regret it someday if I don't.

Lastly, Inspiration sells spanner wrenches for the T pieces, the BC vent valves and the counterlung vent valve. I made the mistake of buying them. They are about $20 each, but are the cheapest, crappiest, most flimsy pieces of junk you could imagine. I doubt I'll even use them once before they break. Avoid them.
