Sounds good to me.
With cordless, the lower the voltage the less power you got to play with. I believe they come in something along the lines of 9.6 V, 12.5V, 14V, 18V, and high end 20-24V. Thus 18V is high high up there, not the tip top but high.
Torque speed or adjustable torque allows you to decide how deep that screw is going to go, or how tight a nut on a bolt will be. It may or may not come in handy, depending on what kind of jobs you got going on. Being able to adjust torque is like having a computer never really thought you needed it, but once you get it you wonder how you ever managed before you got one
.
Other considerations would be battery life 'how many hours can it run on a charge', weight of the drill and yes even color makes a difference.
My number one preference for power tools is Dewalt. Due to that my number one preference in hand tools is Stanley - simply because Stanley and Dewalt are both yellow and black and I desire that my tools match up and look nice together. Is your husband like that when it comes to tools? Most likely not...
...However men are pretty darn funny when it comes to tools, cars and sports teams. I would suggest asking him what he thinks of "this brand" of drill. Or a quick peek at his tool box will tell you if he is a die hard single brand fan or if he has eclectic tastes when it comes to tools.
I think that covers it,
Cheers
