What made you impressed with the? Can you please cite particular examples which made the site different among any other webhosting accounts? Thanks!

I have used dozens of webhosts over the last 15 years, from 5$ a month plans right up to rackspacecloud (this forum is hosted on their servers) and that costs $150 per month as a base, and goes up depending on actual bandwidth and processor usage.

I have sites that have had bursts of 60,000+ visits in a 6 hour period and never seen a slowdown with rackspacecloud (formerly known as Mosso), basically with hosting you get what you pay for.

One thing I would never recommend, is going with a host that isnt well known, as they simply wont have the support capabilities that the big boys do.

If you can afford it, go with rackspacecloud, even at $150 per month, its worth every penny, and then some.
