LOL @ everyone that says get away from SCAL.
Really.... What's the big deal? I have zero issues with it and can complete most jobs as quick or quicker than in any other program.
I don't understand why you would give him the screen. Worst case I'd hold onto the screen for his next order. If he wants to go somewhere else then they can use there own damn screen.
About the only non-subscription option for AI would be to find a CS5 or CS6 version out there with the disc. I am still running CS5 but have added a couple hundred dollars in fantastic plug-ins from Astute Graphics that make it a little more productive. I have considered stopping up to the CC version but as yet have not felt the need. The only thing I wish AI had that it lacks is a true block shadow and cast shadow effect that you can get in the high end version Flexi. You can still build them but it's time consuming.
I'm kind fo partial to AI personally but there is a definite learning curve to get past. Once you do you'er set for life and I use the program for all kinds of non vinyl related things.
