My first thoughts is that FastCGI hints that you need speed and high-bandwidth to handle alot of simultaneous connections..... that is followed by the fact that cheap shared hosts are often slow, throttle your bandwidth, and may ulimit how much ram you can have at any one time. So you should ask all these things to the sales people at the provider, to be sure what you are really getting. I would think that for FastCGI, you would want your own, private dedicated server (or colocation) on a high-speed line.... thats probably around $100/month
