I feel your pain. I'm just a home owner and I've been waiting for so long for new wireforms for my Iron Maiden that I actually forgot they were on order until I saw this topic.
They just did a run of IMDN and somehow my warranty order sat unfilled for the last 6 months...if they were running production on that machine why not get all of the back ordered parts made too?
Stern reminds me of a lot of these companies where it's impossible to get a hold of anyone but if you do the experience is generally good. IT who makes golden tee is the same. they will ignore 5 emails but the one they answer they tend to take care of you.
