Depends on your needs and goals. Personally, if you can afford the purchase price, and can justify the perchase price for a job or two that will help pay for it, then I would purchase it. I have two current dongles, plus a 7.* license and a few older licenses as well…5.5 and maybe even a dongle for 3.5 somewhere.
I’ve loaded the 7. license up on other computers to do low res transcodes. The 5.5 licenses are totally in active, but I could certainly use them to cut with if need be.
The current licenses are obviously my workhorse, but because I own them, if I ever decide I only need to update 1 of them, the other will certainly be useful for years to come.
Scour these forums and you will find all sorts of editors using all sorts of license versions. That’s one of the best things about Avid…they don’t totally lock you out if your version becomes less then current.
That being said, if you purely just want to learn the program, and you don’t have any paying customers willing to fund your exercise, then a few months worth of rental might be the way to go until you get established. But at some point, I would want to have the ability to quit paying monthly fees, but still be able to use my software. I’m not a huge fan of that pricing model at all.
