I've been using an electric Toro two speed for quite a while and find it works well with a few provisos:
-the better the lsp, the better water just blows off. No lsp makes the blow dry a tedious job.
- the high speed setting (200 mph) definitely works better than the low speed.
Cracks, crevices, seams, tires, wheels, calipers all dry off very quickly and the car is ready for the Aquawax/fk425/optiseal/etc immediately after the dry.
The light weight of the model makes the task easy.
If you're a klutz and can't control the tip of the blower, dip it into that plasti-seal stuff to impart a softer protective coating onto the tip.
As I used the blow dryer more and more, I discovered a benefit I hadn't thought of beforehand - the tires are ready for the final dressing much more quickly.
Your suggested craftsman seems to be about the equivalent of my old Toro so I think it'll be just fine and the price is great.
