As an independent Mac support pro, myself, I've seen many horror stories from both big and small developers, leaving users high and dry. On more than one occasion, the support from this developer has been outstanding. Most recently, after a power outage that hosed my own DEVONthink database, they helped me recover a recent backup that, without their assistance, I wouldn't likely have accomplished alone. I would have otherwise been forced to go back to the previous backup, which would have resulted in the loss of all the receipts, important references, client notes, etc. that I had added to the database during that period. They were fast, friendly, and answered me within minutes, despite it being late in the evening in Germany (I'm in Los Angeles, eight hours earlier).
