When I started developing websites, I tried a web hosting site from ebay and the web hosting site claimed that it would give me unlimited space and bandwidth just for $9.99 per year. It also offered unlimited domains hosting. 

I just signed up with the web hosting site and I got my websites (about 3 websites altogether) with it. I was happy as I could imagine saving money from hosting other sites. I thought $9.99 is really good price. My websites were okay for about 2 weeks and then the hosting sites said they are moving their servers and I got to change dns server to new names. I did it and after about 1 day , my websites were running again.

But just after 1 month, again they said they had to move servers again. Now I realized they were not reliable hosting and if I keep on doing like this, I will lose people visiting my sites as well as it would be waste of time to change sites to new server very often.

 Then I hosted my domains with Hostmonster with which I still got many websites and I never need to move over past 2 years or so.

I STRONGLY ADVISE AGINST the web hosting sites on ebay. It is according to my experience.
