Don't worry, I'm usually confused.
Anyway, I think it might be time to replace my at least 10-year old, 14.4v Makita Drill Driver. I've been moving toward DeWalt tools and appreciate my DeWalt miter saw and corded drill. In addition, I was quite impressed by the literal trailer-load of DeWalt tools the builder who put up our new garage and breezeway had -- I kidded him that he should contact DeWalt to do a commercial! So, I started checking things out...
Here are 3 drills I came across (links are to the CPO site because I could find them all there -- ignore the fact that one is only available there as a reconditioned model).

Am I just looking at newer models? The 970 and the 759 seem to share the housings and chucks. The 720 seems to have the newer housing/grip and a (from the picture) different chuck. The specs I can find for the 970 and the 759 seem identical. The 720 seems a bit lighter and has a higher (420 vs. 380) MUWO.
Am I missing something else?
I'm looking at these because I don't think I need much more than a compact. I also think NiCad batteries will be sufficient and I'm not sure I want to pay the increased tariff to go to LiIon. Likewise, if I can get last year's (or even the year before's) model at a good price, I'm sure it will be sufficient for my needs. [i work in an office all day, and while I wish I could use power tools on my colleagues sometimes, I only get to use my tools for weekend projects.]
Any help here would be appreciated.
Thanks, Charlie
