I cost out my equipment in
DCU's (Diving Cost Units ~= to €300.00)
1 Stage Regulator with mineral SPG = 1 DCU
Regulators for Doubles = 2 DCU's
Set of Doubles with Bands = 2 DCU's
Argon setup with regulator and tank = 1 DCU
1 weeks Hotel bill while diving = 1 DCU
Drive to the Lot and back for cavediving = 1 DCU
Trimix fills for 3 divers (15/55, 50/15 and O2) in D12s at 250bar = 1 DCU
1 Drysuit = 2-7 DCU's
1 Scooter = 10 DCU's
Compressor, new = 8-30 DCU's
It makes it easier to figure out, harder for the wife to figure out, and any other tech diver can instinctively grasp the concept

Who, unfortunately, is way past 250 DCU's
