De-Soldering RN42

I have a couple rather pricey RN-42 Bluetooth modules I'd like to salvage from bad boards. Anyone ever manage to de-solder them? How? Don't have a hot-air station, hope that's not the only way.

Hotplate job maybe?

Or buy one of these, especially if you are interested in doing a lot of boards with surface-mount parts some day.
