And whatever you do, don't pay the $79 that some dive shops charge for the Nitrox tables. You can buy a whole set of EAN charts online for about $20.
And here's my 2psi on Nitrox vs. computer. I'm probably going to start a fight here but having done some unscientific tests, I've determined that there is a definite difference in the amount of fatigue I feel when I dive air vs. Nitrox. Nitrox significantly reduces the fatigeu factor for me and both of my sons. So personally, given this experience, I'd get the Nitrox training and either dive tables or rent a computer until you can afford a computer. Diving Nitrox increases your bottom time and, as I said, decreases fatigue in many people.
Disclaimer: There are many people who will swear that Nitrox doesn't change their level of fatigue. Acknowledged. As many others will take the other side of the coin. Let's not turn this into something it isn't.
