Chris, we had a customer come in with a simple broken bolt in an SLG. Replaced the bolt (easy fix), and it worked. Then it wouldn't work no matter what, it just jackhammered and jackhammered it's way out of air. Sent it into DYE, they scratched their heads, and Dave Youngblood himself sent the gentleman a nice new PMR UL. I like that kinda support, personally.
