I've used Dreamhost, Netfirms and Hostgator in the past - not using them now, after I got my own personal reseller accounts.

Netfirms has great starter deals (2 domains + large hosting for $20 first year with the coupon). Drawback : They have their own control panel (not cpanel) and that can be a little difficult to figure out.

Dreamhost is also good value - esp if you get a $97 off coupon for the first year. Again, their own custom panel.

I chose hostgator because they had cpanel, and a decent reputation. Nothing bad, nothing fantastic either.
