Cantrell seems to have a decent reputation, but they never seem to pick up their phone. Anyone have first-hand experience with them? I have gotten through only once a few weeks ago. Last week, I called and left them an email and voicemail, but still no response. I called Gerber and they picked up right away. Gonna get my plenum installed by them tomorrow. Just sucks cause the guy at Gerber didn't sound as familiar with IPD. We'll see how it goes.
