http://hotshottemplates.com/ same as templatedemo all you have to do to buy is just click and when it loads, hit purchase. If you want a unique design you will need to hire a designer if you're unable to do it yourself.
I have always used luckymarbletemplates.com - the templates are ready to use and they will even customize the text logo free of charge. The templates are frontpage, dreamweaver and a couple of others. The customer support and staff is great to work with.
Templatedemo.com is connected with Hostopia or Blue Genesis. The provide free access to these templates through WebsiteOS. Each domain is limited to 3 Flash templates and unlimited Basic HTML templates.
They are really good. I have been using them ever since I found them. I don't think hotshottemplates.com is the same though.
