"Can anyone recommend a tool/technique that will ensure that no data is
recoverable from flash memory devices including USB drives, Memory cards,
and PDAs?"
The only way to be 100% sure data will never be recovered is an industrial metal shredder:

This would however effectively destroy the USB drive, memory card, etc.

If you're looking for a bit nicer solution that doesn't destroy the hardware, try this link:

I've never used any of these tools personally.

Ultimately, the only way to ensure information can not be recovered is to destroy the hardware the data was stored on.
