I had a $200 gift card to a local store, but now its about $105 after a drywall screwgun. My question is what would you choose if you had one choice?

A) Dewalt 102" Tracksaw
B) Dewalt Li Ion Impact Driver/Drill kit ($429 at that store)

Reason for (A), it would be so much easier to cut 4'x8's when I dont even have a panel saw, plus would be easier to store and cut sheet goods by myself.

Reason for (B) Securing 2"x4" studwalls to concrete (treated base of course). Maybe I could borrow one for one time use.
