Hi,
The Kellerman one is pretty easy to use.
You can drag the Wizard control onto a form. It's easy then to set which page the user is on, which buttons (back, next, finish, cancel, help) are showing on which pages and it provides templates for the welcome, action and finish pages.
A link to the website which shows the features is here:
Kellerman Themed Wizard
I use pretty much all the features of it in a few places of our software.
Hope this helps
Richard
