From what I can tell you already have a few reasonable options. (1) Send the crank tensioner in for repair or (2) spring for a Wise tensioner.
For what it's worth, I was one of those people who figured a Wise would be overkill, an unecessary expense, something I really didn't need. It wasn't the price at all; I just felt my crank was easy enough and that if I purchased a Wise I wouldn't enjoy stringing any more than I already did at that time. I couldn't have been more wrong. The Wise is a great little add-on, and since you string for others it'll definitely pay for itself in no time at all.
If you do opt to purchase a Wise, at some point you should still send your crank tensioner in for repair, which will give you a reliable backup in the event you have to send the Wise in for repair.
