I was interested in the Hitachi NR83A2 .. Amazon $279.00
I ended up getting the Hitachi NR90AE ..Amazon $182.99 (free ship), I saved 100 and it shoots 2" - 3 1/2" nails ..
I decided from friends here and others I know outside of here . One guy I know frames houses all the time running a crew all using the Hitachi NR83A2 ... no problems ,,, no jams ever but insist on spending the few extra bucks , always buying the Hitachi nails . Decided to go the full round head to (Mac,,others) .. I'll just wear eye protection for the flying plastic and watch who's around me ..
