2 years ago i put together 70-80 deep boxes with a drill and screw gun, and 7000-8000 frames with a hammer.
i'd never used an air tool until last year. don fatbeeman let me use his to secure the nucs we were buying....i was very impressed. when i got home and needed to put together a bunch of equipment, i went to sears. there was a 3 gallon compressor on sale for $99, and a 3 piece tool kit (crown stapler, brad nailer, finish nailer) for $120. i've been very happy with all of it.
