I currently use internetbs for domains, but quite often I dont want to renew a domain for whatever reason, and park it. internetbs change the name servers the day it's due for renewal so I lose the benefit of possible traffic for 60 days (or however long it it) before it's suspended/cancelled. I would be transferring the domain over before it expires, of course. What registrars leave the domain functioning while in the expired/redemption period, and ideally, makes it easy to transfer the domain back out if required? I have used vidahost for domains in the past for example, but their transfer out process is manual.
