Windows Virtual Server hosting

I've been using VPSLand since beginning 2007, Its great value for money if you need more flexibility from your hosting than the standard web hosting that other companies offer. They're uptime is great and the few minor issues I had with them over the last 20 or so months were quickly addressed. Also helps that they have unlimited free online support via email, and they've always responded to me within a day or 2 with a solution!
I'd let you make your own mind up, also you need to consider if you need VPS hosting or if the standard hosting that can be more cheaply available.
I do think however that with the web becoming more and more powerful it will become more necessary for people to go for the more flexible options of VPS hosting.
