If any newbies are thinking of giving this a try, I'd recommend High Country Hosting. When I read through this tutorial about 2 months ago, I signed up for a basic plan under $10 and they installed the Comus and TTT scripts for me (free/skim versions). I was up and running in about 24 hours.
After a few weeks, I decided that a TGP wasn't the route I wanted to go, and I've been doing free sites instead. But this tutorial was very helpful. Big thanks to the author and all the contributors. I know I'm going to come back to this and give it another try in the future.
Anyways, if anyone is looking for cheap hosting and can't handle installing scripts, check these guys out. I'm sure if you drop them an e-mail and mention you're from the GFY boards, they'll give you a good price.
