I for one would only choose a host who uses cPanel as it is the easyest and most intuative to use i find. In the new version there are a lot of nice Javascript features plus cPanel is very powerful and well layed out.
If you read the OP ghazal is saying she wishes to start her own host and would like advice on what is required, not what is a good host.
Oh, I'm an idiot, it's early in the morning. I thought I read this thread yesterday but didn't submit a reply therefore I just assumed I knew what I was talking about without reading the post again, sorry.
