I've had domains since they were free (remember those days) and hence back then they were the only game in town. After years of bad service and problems I moved to GoDaddy and have been happy. I figure that if I need a human it'll be tough at GoDaddy, but their website is powerful enough for me.
I'd pass on this offer even it was 10k miles. 20k miles I might think of it, but even then I'd have my reservations.
