seriously, unlimited doesnt exist. Going for unlimited will place tighter restrictions then going for a limited service.
for example, one popular host offers unlimited everything, but then has secret 1000 table limit, so essentially only 3 websites max as installations such as joomla use 300+ tables. others can have such tight inode limits that using just 500mb can hit the limits.
my advice, find one that offers what you need, not one that pretends to offer everything, and gives you nothing.
Oh, and one final piece of advice. I just took over a company that was selling "unlimited" for 15 years. the guy told me that anyone that reached 1gb hdd was instantly kicked out (no refund either). Now that I took over, i placed everyone on 2gb limit, it is DOUBLE what they had before, yet noone is happy as they still think that before they had unlimited.
I have been in and around webhosting takeover for 2 years now, and there are some unlimited providers, that kicked out users at 500mb hdd (no refund) others terminate anyone that has 2 backups of their accounts (hostgator does this for one) they do this as a way of keeping HDD usage down.
so good luck.
