Early builders
For those of us that are the early builders of the 12, yes there have been some problems. They seem to get correctd fairly well, and without great waiting. I'd say by now, if you start on the first kits, you will find they will pretty good. We are finding the problems, and they are being corrected. If you are missing or BO on an item, you can usually find plenty to do until the part gets there a few days later.
