None of them have been built into sites. ilove/luvuptime.com may make good domains for name servers. While snapshotstorage.com/net/biz could be used by a backup hosting company. But, really the choice is up to you.
I'm looking to get $5 per domain. Or, take them all for $20. Domains are currently registered through Namecheap.
