Pay once, get a server for life. Servers start at $35 for a 1 CPU / 512MB RAM / 10GB SSD. Watch their Twitter account because they have coupons for 50-60% all the time. On Black Friday they had coupons for 90% off.
You get what you pay for. Don't expect stellar customer support or blazing fast boxes. I only use these for really basic things. I have one running GitLab to back up my code, a couple running Cloud 9 so I can dev straight on the server, and one as a proxy for when I'm on public wifi or something. Don't think you are going to run your company's web site on these servers.
