We have more than 30 domains (mixture of .co.nz .com.au and .com) which are currently registrar'd with Freeparking (who we have supported for ever until now), but we are ready to vote with our feet as the quality of service and support decreases and administrative errors are increasing.  We also get unsolicited phone calls from them which I reckon is bad form from a security perspective, and the calls continue even though we have asked them to desist.

Any suggestions? 1stDomains? Metaname?
