Hi guys. Just found this site, have searched for a similar question and read as much as I can but I still can't make a decision. I'm needing a hammerdrill for drilling into masonry where we lock art down using a 3 point system. Pretty basic hole in the wall type thing. I'm going with a combo kit because I want a smaller driver than my 18v standard dewalt driver, which is a beast to carry around (wont always have to carry around the hammer drill, just when we run into block wall). Also, how beneficial is the 3.0Ah 20v vs the 1.5Ah 20v? There are some really nice +1 deals with the 1.5Ah version of the top one.
Anyway, I am considering these kits. Will I be happy with the compact set?
