i am with domainRacer for about a year now and i am pretty happy with their service.
The speed is good, The customer support is good but their technical knowledge is terrible.
for months and months,, my customers keeps getting constant email issues, emails that does not comes out, emails that does not come in.. this happens at least once every 2 months..
but it's a small issue compared to problems i had with the likes of Genhost.in .
i'm going to stay with domain racer..
not bad at all.
