Smart Device Extensions / .NET Compact Framework

I've finally gotten around to playing with the .NET Compact Framework, and it's pretty neat. I just think it's too cool that I can use the same business logic from an ASP.NET application and use it on my iPAQ. I still have to get into working with the syncing and all that stuff - but it's neat.

That being said, does anyone know of any good resources and/or control libraries out there? There are a few things - a tree control, for example - that I need in a little application I'm working on which don't seem to be a part of the base classes. I figured I'd see if anyone knew of something good before I reinvent the wheel.

Thanks!
