I guess it depends on a few things as i see it my websites are one of my business’s and i have to have ultra reliable hosting i cannot have any major problems with the sites as my customers will go to other more reliable sites,i may pay more but try and get the best you can as it is cheaper in the long run.
the cost of reliable vps usually cost me about 10 dollars a month,maybe i will go on buy multiple web hosting, to save some cost while it can also decrease the stress on one hosting.
