A buddy and I are almost ready to drywall my basement (abt 1500 sq ft
ceiling + walls = abt 110 sheets of 8' drywall, or fewer if we go 12').
I am leaning towards buying one of two Dewalt screwguns, the DW272 or
the DW260K. I have some questions, though:

1) I like the reviews of those guns, but neither one has an automatic
feeder. Am I going to regret hand feeding?

2) I can't tell what practical difference the guns have. The 272 has
0-4000 rpm, and a max fastner size of 8. The 260K has a case, 0-2500
rpm, and a max fastner size of 12.

3) Assuming I have 2-3 guys on site, is one gun enough?

Thanks
