Hi Steve,
I feel this is a good product if...
- your looking for full blown framework as opposed to just a toolbox of classes.
- your were formerly involved with flavor of Codebook in the past
- you dont mind following a lot of conventions
- you got the time to tackle the learning curve

Plus too, I've never had something I couldnt solve when working with this framework... but I will admit that there is so much in it nowadays sometimes hassles take a while to track down and find where to handle correctly (as in the subject of this thread).

As far as seeing the class structures, give the folks at OakLeaf a call and see if they'll let you review the documentation. I was able to check out the Developers Guide from a consultant before I initially purchased it for the first time over 2 years ago... this doc is now several hundred pages long and has most of the core classlibs shown in UML style class diagrams.HTH
