I have dived at the same altitude as Colorado for more than 30 years 
now, and have tried everything.  Aside from some of the Decomputers 
that compensate for altitude, the best solutions are:
1) BSAC tables:  these are easy to use, conservative and work 
exceptionally for excursion diving (diving at a different altitude 
to the one that you live at, i.e. are saturated at). These are 
Available direct from BSAC in England.
2) Buhlmann tables:  these form the basis of the algorithm used ny 
many of the decometers on the market, particularly those form Europe.
If you need more info, let me know.
