who am I missing?

edit: to clarify what I mean by passable, I mean producers who put out consistant batches of high quality rosin. should have probably been more clear in the OP. companies that don't make mids/boof. this is somewhat rare in MA for whatever reason, but there's a few decent operations from my personal experience. and my experience with GC has been somewhat inconsistent, but they are still a fantastic value proposition for the price point.
