I have a C30 right now... Had a 22 and 27 as well.
I've been very happy with them.
I used to live in LA and send my wife by the plant to pick up spare parts. They were always courteous and reasonable.
Never met Frank Butler, myself. Hope to shake his hand one day and say "thanks" personally.
My understanding is that he still handles all warranty issues himself.
