Hate to break it to you...
They all build a set that'll suck, for someone, at some time.
I've been using unlimiteds service for the last five years or so, and generally, I've been happy with their customer service. Had a little trouble going thru them getting a ts chip reburned, but it did get resolved.
The injectors have all been fine, and this last set was really only suitable for cores, so they contacted me before doing any work.
I have noticed that there seems to be new guys answering the phone in the injector shop the last couple times, for whatever that means.
Rosewood does have a good reputation, also.
