Recommended modules for Parent-Child trees?

[Hero Zzyzzx]

I'm looking to implement a DBI-backed parent-child tree in perl, and I'm NOT looking to reinvent the wheel, AGAIN.

Do any of you have any favorites on the CPAN? I'm looking to do child/ancestor/sibling queries and manipulations, and have some kind of help on output (like figuring out what "level" an item is at), though I'll be using HTML::Template for display and CGI::Application for "flow".

A few I've been looking at:

• Table::ParentChild
• Tree::DAG_Node
• Sort::Tree
• DBIx::Tree

I'm sure I'm missing some that are worthy of consideration. What have you used? Likes? Hates?

Thanks!
