Reliable, fast registration, and no behind-the-back stuff
This is not a budget registrar, though in the past they were cheaper than Network Solutions (one of the reasons I went to them). This review is from the point of view of a small domain 'collector', not a 'domainer'; I do not know what kind of support they have for sales and marketing. Good basic network services for registered domains (DNS, email forwarding, etc) but recent changes to their 'control panel' for those functions have made it somewhat confusing and harder to use. The two customer service issues I had were handled quickly and professionally, if a bit tersely.
I have researched many domains through them, and not once had one purchased 'out from under me', even if I dallied for a day or three. Never had a domain purchase acknowledged then 'sorry! its already sold to someone else' as happens with certain other registrars.
You may pay more but you get quality service with no underhanded tactics.
