I just hand regged a "chancy" domain today, using the $2.95 GoDaddy coupon. If it doesn't do well, I can allow it to expire without worrying about allowing an expensive domain to delete.
Sometimes I hand reg domains related to my writing, for example, the book title in my siggie. These are not high-ranking, high traffic terms, and I know it, but I try to choose titles that are memorable. It's great being able to hand reg these kinds of titles.
I AM regging fewer domains these days, though. It can get expensive, especially with prices going up.
