I've been using them off and on for a few years and I also use Network Solutions for some domains..
The support by phone from the US is tops at DomainSite but I found out
the other that day that just leaving them parked there untill I change
the ns1 &2 they had some of them forwarded to a search site that was
running scripts and loads of popups which will get the domain
BlackListed at alot of places..
As soon as you register it they forward it like the link below..

So Beware!
Great place to buy them but make sure ya point them to one of your
servers...
