There's an article I'd suggest you read over on MousePlanet (don't hurt me MiceAge folks!) by Mike Scopa which kinda sold me on the idea of using the plan to begin with. Here's the link... http://www.mouseplanet.com/articles.php?art=ms060602ms. Between Mike's views and Kevin Yee's views, you should be able to make a choice that works for your group.
Good luck to you!
