I use MS Live and, to be quite frank, i am fed up with them already! I'm not going to complain about their customer service as it's top class, plus you get free domain name, etc. However i HATE their design program. It is OKay to get your site online as they have a couple of nice templates, however now I am at the point where I want a more professional layout for the site.
It is VERY easy to create a professional looking website, I use premade layouts and then <b>heavily</b> modify it. I believe that you are allowed to upload .aspx layouts to OL (basically, in a nutshell, .aspx is exactly the same as html, just has another file extention at the end
); however I will have a look into it and then tell you my findings!
p.s. if I can have my own template on OL then the new look site will be online next week
