IR for Air...Snap-On or Dewalt for Cordless.
My Snap-On guy has a used Impact box if you want me to take a look, generally they are quite a bit cheaper then new, Im betting I could get it kitted if you wanted too. I personally dont want to go back to air after cordless.

Snap-On gave me a quote for ya today Brett. 426 tax included, but he figures in a week or two he should have some more at the sale price so they will be 50-60 cheaper.

snapons got a 3/8 cordless with 230ftlbs, btw... but 369 new with 2 batteries...
hell i got a used IR ill sell ya for 15 bucks that works, but needs a rebuild kit, in the neighborhood of 40bucks or so in parts...

The plastic knob and buttons look a little on the cheap side but other than that it seems very good. Lots of power too.Well, I ended up getting an IR 2115TI 3/8" Titanium
