I have had local bike shops jack me by giving me incorrect spoke lengths. When you're a newb, you don't realize it till the spokes keep breaking, I've found spokes that shop has put in where half the threads are showing. Other times, they have substituted the DT Swiss I ordered with a few no name spokes I couldn't even identify after breaking. MIGHT even be the reason the spokes are breaking immediately after the shop re laced the wheels with new spokes. Happen to me and like the OP, I gave it a try and never looked back. 20,000+ miles vs 500? No brainer. I have actually had one wheel built at the shop that didn't last the first 20 miles of a 40 mile ride.
Correct me if I'm wrong-"You're assuming that the shop put in the wrong length spokes and that's why simply measuring what he currently has in his wheels won't work"? With that assumption, yes, by all means use the link you provided and get the correct length. I've only done a few wheels and have always been able to measure the existing spokes with no problems. I use a home-made wheel truing stand and try not to over tighten and keep the tension as even as possible without a tensiometer. It's a long drawn out process, but so satisfying when the wheel is true and you can ride the sh.. out of it with no problems.
