Hey Wayne,
Here's what I found. I am seriously considering building the "ApplePie" design. It seems the simplest of all the designs and they say that most who try this design, even first-timers wind up with a usable dinghy.
Here's the URL to a guy who built one:

He referenced the site called duckworks magazine which actually has a lot of really cool little projects on it. If you look in the designs section of the archives from 2002, 2003, they have a lot of free plans for boat building.

I'll probably be building my sawhorses and prepping the garage for the project this weekend. Let me know if you get started on one, it would be cool to share insights as we go along.
