The lower you go in price, in general the more problems you’ll have with overselling, poor management, poor support, etc.
After coming back to this thread and reading some more comments, it sure looks like I could save up to $3 a month over what I pay for cheap VPS at Ramnode, but in all my years of being a Ramnode customer, they haven’t pissed me off, and their support has always been excellent. I have no desire to move, and I’m somebody who has very little money, so cheaper hosting would make a difference.
