I own a number of domains with ".net", ".com" and ".org" TLDs, which I would like to keep and renew. The thing is that I would like to change the company I had them parked with (they fooled me once already). Companies like yahoo or godaddy who sell domain names, don't actually sell their ownership or technically b#llsh!t their customers in similar ways, so you will be trapped by "their services". I just want to park the domains I own

Which companies would you suggest? Which other gotchas should I be wary of?
