Powershell provider for Sharepoint 2007

Would a Powershell Provider for SharePoint 2007 be worthwhile or is stsadm.exe sufficient?

There is a PowerShell provider that I've heard some good things about. It's available on CodePlex; however, it doesn't yet support MOSS 2007. That said, I've found using the SharePoint object model sufficient. If you don't want to dig into the object model, though, I recommend both Gary LaPointe's stsadm extensions, and his newer PowerShell cmdlets for SharePoint. Both are available via his blog.
