>> Is it possible to sell unlimited space and bandwdith at these prices?

There is no such thing as unlimited bandwith, If that's possible, probably Google shouldnt spend millions in there hosting expense and should just buy a $3-$6/month Unlimited space and Bandwdith plan.

>> Are those $1/month plans without unlimited bandwdith and space true? can they provide?

To understand these question the right way, one has to change the mindset from a webmaster to an hosting company staff or owner. Say you start a hosting company, to compete in the saturated market you obviously keep the prices low. Now the question arises is how you Should manage your earnings? would you spend 50% on marketing, or product development or security software etc. This is exactly what differentiate the good and the bad. An evolved and destined to success hosting business would first try to give their best to the available clients, so they build a client base. Develop servers with good security systems and high Ram's to give fast hosting. For publicity, one may understand there are creative methods which are very effective but cheap. Any business in the initial state is more about building relationships, than just pure money. Every webmaster should understand here, that any hosting company giving unlimted bandwdith and space would sooner or later tell them to upgrade due to resource usage or impose hidden limits like sql databse limit, sql process running limit, file upload limit, file size limit etc. A smart webmaster would first understand his needs of hosting, Say a webmaster needs 50 Gb bandwdith to start with, he should go with a company providing it for cheap price with quality support, uptime and 30 day moneyback guarantee. Not pay more for unrealistic unlimted bandwdith and space, etc.

>>How can a cheap web hosting company like above, keep its budget?

By maintaining technical and support costs with the earned money and do marketing only with hard and creative ways. This may be slow in bringing hosting clients, but very good in mainaning the current clients. A win-win situation for the webmaster as well as the hosting company. Most of the hosting clients also come as referred by current clients. If the service is good, every customer is more than willing to put your name out there :-)

>> How to find these genuine companies?

Sorry, no answer here. The only possible way is to try it. Look for some signs like 30 Day money back guarantee, 24x7 customer support, 99.9% uptime.

>> Can I depend on web hosting reviews out there?

Yes, you can but the biggest problem is that 90% web hosting review site out there is owned by a hosting company, which would say good about that one particular company and bad for the rest. Quite unbelievable, but true!!!
