He's always been pleasant with me. Timely, hell no, but pleasant.
Anyway, now that there are people here who are expert in repairing Church mics, I wouldn't hesitate to buy a pair in the yard sale.
He has his defenders and detractors. All pretty well documented here. I wish he had been pleasant with me, as well as timely (definitely not even close), but he was just plain rude at times. He deleted most of his posts here, many of which showed the same ill-mannered tendency.
As for repairs, as far as I know that is confined to cable repair. If you have problems with the capsules, or a pre-amp, you'll still have to go to the source. I had an EE friend try to take a look at a Church pre for me and he said there was so much gunk melted into the box (presumably to prevent theft of his incredible designs), that is was not workable as far as a fix. Just my two cents...
