SharePoint V3: Administrator Reports; Utility

I often get asked about how to obtain useful administrator reports for SharePoint. Here is one inexpensive utility to evaluate:

Admin Report Kit for SharePoint 2007

Pros:
- Low cost
- Hierarchical reports
- Can export reports to several different formats
- Reports can save you a lot of time if you try to write in TSQL

Cons:
- Doesn't support rdl publishing to Reporting Services
- Doesn't provide join to AD object enumeration (expand AD members per securable)
