Ah, yeah, with that many to do I'd want the battery ratchet too I think.

I have an electric impact as well.  For around the shop, air is easy (I 
close off a valve and the compressor doesn't lose appreciable amounts of 
air between garage sessions), so it doesn't get used.  At the track, the 
battery impact is easier and does most everything I need it to do.

But the electric impact is in the trailer for when something goes wrong 
with the battery impact.  :-)
