You hit it right on the money. I can't imagine many diy'ers using a manual nailer especially with very hard exotic floors--
Very hard work I've used a combination of pneumatics in the past and also found the M111 FS to be the most effectibe one out there.
Incidentally folks looking for the M111 FS--look on Ebay--they're constantly buying and reselling the tool. It basically comes down to paying for shipping and handling. Buy it one month--place it back for sale on the next. Or you can always rent from the home centers for $140 per week or therabouts.
