D3 $200
SK5 compass: $40
pressure guage: $65
$305 you have all info you need. (probably can get it for less)
For a bit more you can have a standalone computer around what, $400-500?
All bells and whistels: $1000 upwards
many gasses and such: $1500 upwards
The real question is what do you want a computer to do for you and how much are you willing to pay? On top of that think about what it would cost to repair, how long it will take and bear in mind the pain it will cause if you loose it...........
Not to speak of redundancy.... all requirements in ONE package.....
