You'll have to factor in, they have to hire new techs to take care of the expanded service. The current techs may or may not know how to run windows servers so even more techs maybe needed. Also your paying for premium service, PowerVPS wont let you down. Yes with 99/month you can get a dedicated server but can you get the support they offer? Power-2 also offers MSDE. If I ever needed to get a windows VPS I certainly go with PowerVPS without a doubt.
