I used dockbuilders as well and was happy with the service and results. The salesman was very helpful in making sure I had all the screws, brackets, etc. for my dock.

There are a few sample docks kits to see at: http://www.dockbuilders.com/floating-dock-plans.htm

I chose the "12'x12' with optional gangway" with the 6 smaller floats instead of the one with the 4 bigger floats.
