As I said, price shouldn't be the main decision factor when you choose a web hosting.
Why?
Well, look at this examples. [

Amazon loses $1,104 every second that amazon.com is down.
Google's 5 minutes outage is reported to have cost over $500k.
Have your site unreachable makes you lose money, directly or not.
And more. For example you can lose potential customer, it can adversely affect your reputation, you can't receive emails.
Imagine you are earning $50 per day.
A cheap host can guarantee a 99.5% of uptime, but actually it can be also lower. 99.5% means 7.2 minutes/day of downtime, which are 1.825 days/year. <<URL snipped>>
In this way, in one year you can lose about $50*1.825 = $91 per year. But as I said, there are more things other losing money.
A good reliable web hosting can guarantee (and usually maintain) 99.95% of uptime, which is 0.1825 days/year.
Hence, you lose $50*0.1825 = $9.1 per year.
It is an interesting example that can explain visually why web hosting is so important.
If you can, pay a little more, but you'll save time and money.
