I know of many ISPs (personally, I know of dozens, though I'm sure several hundred of them exist in NA) that are X-small under IPv4 and don't have any IPv6 due to the added expense of moving up to small. yeah, it's not a large sum of money, but with increasing regulatory and network burdens, "bonus" areas like IPv6 are cast aside. Smaller blocks, smaller fees, I dunno, I'll let someone else figure out what's best there.
