Check Harbor Freight... they have some excellent deals on hand power tools, and actually I bought some of their
Chicago Pneumatic brand air framinghammers (straight feed)and shingle nailers (round feed) tools, and they take the same nails as a Stanley-Bostitch. While I paid a lot less for them then the major brands, they really work well. Made in China of course. But I'd put them up, side by side to some of the better brand names out there.
Besides, Harbor Freight has a bargin bin where you can spend tons of money on things you will never use, but look good hanging on the shop wall...
