GoDaddy's Economy plan is presented as though you can't sign up for a month-to-month payment plan (the lowest price displayed is for a three-month minimum sign up period), but once you add the plan to the cart, the one-month plan appears. We're glad the option exists, but we do wish it were easier to find. We couldn't find it until a GoDaddy pointed it out after we complained that the option didn't exist in a previous version of this review.
A dedicated server will likely cost you more than $100 per month; it's definitely not cheap web hosting. The benefit? Your website lives on a server all by its lonesome, so it takes advantage of the server's full resources. You'll probably need to handle firewalls, updates, and maintenance yourself, however, unless you opt for a managed server, which costs even more money.
