never go with the quantity... go for quality. also do some research on google, read reviews in forums. check for how long they are in this hosting business? How good/fast is there support? and always read the TOS (Terms of service), see is they offer any SLA on shared hosting or not. check there domain stat on who.is, to confirm when there domain was registered.

There is a lot of things to consider before you choose a good hosting provider.
