It's time for me to seriously upgrade from a Black & Decker 7.2V(Target) drill to a new one with more power,speed,etc. I'll be using the drill for basic things such as putting up blinds to maybe down the road doing a deck,kitchen,sheetrock,etc. By know means am I going to build a house with it but I do want a drill that will be able to handle small to large projects. I'm looking for something that is lightweight as well.

I picked up a Dewalt 18V (DW959K2)from Lowes on sale for $119. It turns out that it's some sort of model that Lowes doesn't even carry now. I don't know if it's an older model or what. It doesn't have a rubber grip like the current Dewalts leading me to believe that it may not be comfortable after extended usage.

So my dilemma: Do I return it and check out one of the newer XRP Dewalts like the 14.4 or reg 18V(same as mine with grip?) or should I check out something newer like the Makita Lithium-ion 3.5 lps 18v,Panasonic 15.6 (3.5 NI-MH) or other brands? Help.
