PEAR Classes -- worth it?

[mikepurvis]

I already use PEAR: DB exclusively for my db-access, but I've been intrigued by the QuickForm, HTML_Table, and DB_Table.

Is there anyone here who's used these? Can you comment on their usability and extensibility? What about the validity of their output, and ability to style?

I have a couple nasty load-view-edit-save screens that I'm about to start work on, and I'm just curious if these tools are worth trying.

Thanks.
