Our own Lynn Terry here at SSWT uses them!
THAT ought to say something!
I used them about 2 years ago and was disappointed with their customer support which had alot of problems back then.
BUT ... Now I'm hearing from ALOT of people (like Lynn) that are now using them and it seems that everything at HG is 1000% better than it was way back then.
Shortly, I'm gonna start using them again for a couple of smaller sites. If you have many sites, it's a good idea to spread them around a bit, i.e. different hosts.
The "price is right"!
My 3 centz anyway ...
