I did the math to see where the break-even between turbo and NOS are:
Q: How long will the 10lb. bottle last?
A: This largely depends on the type of nitrous kit and jetting used. For example, a 75 HP Power Shot kit with a standard 10 lb. capacity bottle will usually offer up to 15 to 18 full quarter-mile passes. For power levels of 125 HP, 7 to 10 full quarter-mile passes may be expected. If nitrous is only used in 2nd and 3rd gears, the number of runs will be more.

Q. How long will a bottle of nitrous last?
A. That depends on the level of power being produced. The formula for calculating your nitrous usage is: 0.8 lbs N2O X 10 seconds = 100 horsepower. I.E. If your system is jetted for 100 horsepower it will use 0.8 lbs of nitrous for every 10 seconds of usage.
One can calculate the break-even point if you have the two kit and installation costs: (It is SA Rands based, but I'm sure the comparison is similar using pounds

Kit R16k install: R4k = R20k (semi pessimistic)
Turbo Kit and install: R50k (way to many variable to be accurate - but this is optimistic for new parts)
At R255 per refill and 15 boosted runs per bottle - you can run 1750 boosted runs to break even.
EDIT: Lets consider the 2nd hand route and free install: NOS R3k - Turbo R15k - break even is 700 runs
