If you're looking for something flexible, powerful and straight up good, http://www.goscomb.net/ http://www.goscomb.net/ gets my vote. Not the cheapest, but definitely one of the best. We used them for a dedicated pen testing server, and when you're running port scans and exploits across the Internet they were surprisingly trouble free (other hosting providers had their IDS' go off, had filtering for various ports or would just randomly shut our systems down for 'hacking', despite us telling them what they were being used for. We've replaced it with a beefier office link and a smaller VPS (also from Goscomb). Goscomb are UK-based, so you might find that it's less suitable for Asia-Pacific users due to latency.
