Please help me in choosing web hosting

[0as]

Hi everyone,
I am sorry for possible offtopic, but I need your help in find new web hosting provider as soon as possible, because my current host (ixwebhosting.com) is kicking me off, they say 'your account is using a lot server resources', but my website gets only about 200 visitors per day and my disk usage is 1500 MB (maybe they do not like that?)

Anyway, what would be your recommendations for getting reliable web hosting? Where are you hosting your websites? Are you happy with your providers?

I am now checking Hosting24.com - First Class Web Hosting Services - offer looks very nice, but is it real that they can provide unlimited disk space?
I have contacted them about this question and they say something that "These days 500GB disk drive costs only $30 per month, so if some day we will run out of disk space we will simply add new 500GB disk drive with almost zero costs and you can continue uploading without any problems".

What do you think about it? Maybe things have changed in last 4 years? With my current provider I get only 2GB of disk space for $10 per month..
Any ideas and suggestions are much appreciated.
