I have servers that are in datacenters around the world starting at $5/month for a shared server. Also right now I have some I can give out for free to get feedback for my services. If you are interested in giving it a try, go to
https://supertuxkartfans.gameplayer.club/HostSplash, choose the shared plan, and when checking out choose the "offline" method so you don't have to pay. Lets promote STK to other kart fans!
