These prices are really cheap.

For Europe I can vote for Hetzner, very positive experience with this network / data center. As long as you know what you are doing in terms of your software/operating system, they provide very solid h/w and network.

If you want to go the lowprice route Hetzner might be your best bet. They have pretty decent hardware for a superb price. Please keep in mind that they have some Layer2 security features enabled so that you need to workaround it if you want to create KVM/Xen/OpenVZ vps. All this is well written in their wiki https://wiki.hetzner.de/index.php/Virtualisierung/en

Since some months they also provide DDoS Protection though I haven't seen any reviews yet.

select a dedicated server provider with enterprise quality, DDoS protection and free IPMI.

There is no need to choose a host with the "fastest" ticket response time, but choose one who you feel you communicate well with. Make sure the host has the payment option your looking for. I don't even think twice about a host that doesn't accept paypal.

That cannot possibly be a decisive factor for reliability of a web hosting company...

hetzner has a Nat network they don't provide any network configurations on subnets if you are familiar to network routing specially via mikrotik router then hetzner would be best choose if you are not familiar to network configuration so go with OVH

Because a host accepts or does not accept a certain payment method does not make them good or bad.

I stopped offering Paypal as a method for 12 months due to the fact they had a habit of cancelling subscriptions without any authority from me or my clients and all you get from them ' just set them up again as it will not happen again' until it happens again. this makes me look unprofessional and messes me and my clients about.

We again offer paypal after researching PayPal Billing Agreements, which we had to sign up through braintree to set up, but it means if a Paypal Payment is missed we can capture the payment from our end. this is far more stable than the PP subscription system

Checking out offers section of the forum would be beneficial to find out best hosts offering services probably apt to your requirements.

you can easily find it but the important thing is that which vertulazation would you like for

you can find at wholesaleinternet the same server for about 80$

Have you checked ,

For US: Turnkey Internet
For EU (Germany) : Contabo

They also have good server solutions

Yes wholesaleinternet , nocix & joesdatacenter also good (All are Kansas City DC Providers as i remember)

Is "good" based on personal experience?

Another way to go would be to use Vultr, Digital Ocean or Safeway to provide the VPSs, and you could add the "Value Add", if you are merely looking to make cheap VMs for sale I doubt you can beat their prices, and you can auto-deploy them via API.
