This is the first time I have heard of this company. They have some powerful design tools.
If you are looking for a better price, you can go elsewhere, but it seems like these guys offer some good packages. If you have the money to spend, I would go with the advanced package.
Ease of use: I watched their intro video, this looks like any layman could build a website with these tools
. It looks like you could also use your own CSS if you don't like some of their layouts.
Plus with 14 day free trial you really cant go wrong!
