Let us know if possible where you got the vps from and how much you paid it ? And does that vps include cPanel/WHM ?
I bought Un-Managed VPS from one of the sales thread in this board. I didn't have much budget so I only spend less than two hundreds (actually it is only a hundred and few dollars). I didn't include cPanel because I already found another ways to manage my VPS. I am glad there are lots of resources to help me manage my Un-managed VPS.
