Bryan, I think for the Iron I'd like to get my hands on one to keep. If it has to be a serviceable one.. that would be 'ok', however the preference [due to cost] would be to get a un-servicable one, granted its not TOO warped or something. I would use this for mock up and assembly testing of the actual mount housing etc.
