I would recommend HostGator. They have plans starting from $6.95/month (50GB disk space, 200GB bandwidth). I moved to them a few months ago because my previous hosts’ server response times became unbearably slow and till now I’m very satisfied.
There support is very responsive. I have mailed them several times asking different stuff and every time they responded in a couple of minutes.
They will even assist you in transferring your account if it’s currently hosted on a different provider.
