I've got the SuperPro - adjustable up to ~125W, which I have (so far) found to be superb. I used the hot air attachment for reflow soldering the resistor pack for the button LED hack (add lots of flux, solder paste, place component and heat until the solder melts - the surface tension pulls the component into place). It made quick work of it, and ended up being the easier part of the install.

It's also great for heatshrinking, desoldering etc, and the convenience of being cordless and very quick to heat makes it a joy to use.

One thing that I would say is that it takes a little while to get used to the hot air jet that shoots out of the side of the tip...you need to learn to ensure that it points up and away from you and the work.
