If you are just using them around the house Id go for something cheaper...We have a tech at the shop that has a Cambell Hausfield(sp???) and beats that thing like crazy and its still hanging in there. i think it was less than $50.
My most used is probably th 1/4 air ratchet or 3/8 impact.

Heres a list f my air tools and prices:
1/2 matco impact $150
3/8 matco compostie impact $250
3/8 bluepoint air ratchet $30(used off thetool truck)
1/4 mac air ratchet
snap-on dye grinder $90

Next on the list..Air hammer
