My current site (www.gamershock.com) has ran out of disk space on destxhost.com.

My current plan was:
6 Gigs space
245 Gigs bw
cpanel x2
$2.99

I need something which can easily beat that, and will keep my site up with no problems. I'll also look into reseller as I heard it makes it all easy to host my sites, but still puzzled on what to choose.
