Matt, is there any way to get this unit with a seven year old decompression
algorythm that does not work ,  a huge pricetag, training by a dyslexic
idiot, and maybe could you also lie about the bottom time to make me fell
more "at home".

Is it possible to Tai Chi breathe this unit? Could you maybe rig it so that
there are more ways to screw up, and just for old times sake, put me one
together in somebody's garage with a good civil engineer present turing the
screwdriver, maybe a concrete insprector or a bridge guy - a "real
engineer".

I want to spend some real dough here - could you ship me one with for an
extra ten grand and charge me about 3 grand more for training, and could you
rig it so that I have to dive it on air until you say I can dive gas?

Also, could you forge me up some ppo2 and profile graphs so I can show them
to the guys back at the dive club? Oh, and could you please paint it yellow?
