I used Contabo and Ionos. Ionos if fine for the Price at their VPS S (smallest price 1$ oder 1€), nobody can make a better price with fees. But Ionos larger capacities are really stupid in terms of power per dollar. Contabo is there much better. I need to mention when you use their VPS S then you need to modify your setup script because it does not want to start even when 512 mb are enought.At least when you have no giant mail server and have no other services on it.
