You don't need to break the bank, but it is worth it to buy something decent that will last, in my opinion.
Dewalt or Milwaukee would be solid choices. The company I work for purchases Makita combo sets. We beat the piss out of them and have burned our share out, but they would be great for use at home.
A simple pocket driver is all she needs.
I end up using my Bosch pocket driver much more than my big drill.

How much wall space can there possibly be in the kitchen?
Organic cordless?
Ma dick :|
TheMMAn -Haha yea she might need a lithium battery. Try snap on brand

Passive, you need to leave the phone at home one day. You seem to live connected to a pc or phone screen. Just saying bud.
DeWalt
In case she does slap a dildo on the end of it
No need for 24v or even18v for her. Get the smaller 12v cordless drill. It will handle all small projects and is a lot lighter.
TheMMAn -Ha!
Knew this was coming!

sewich - Dewalt 20v
She would probably like a big black cordless drill.
iqwrestler - Milwaukee or go fuck your mother.This

I've been running a 20v dewalt daily for about 2 years. The collet in the impact driver stopped working about 3 months ago and drops tips all the time. These drills might last an occasional user a lifetime.
Any drill would probably be fine for her. If she is going to add more cordless tools in the future, brand becomes important for battery interchangeability, but just for a drill only, even a lower end black and decker should be fine.
I swear by Makita.
The best drill is to grab a whistle and have her run laps in the kitchen.
Ridgid. Lifetime warranty on drill and batteries.
Dewalt 20V Lithium Battery
No love for Makita?
Milwaukee makes their 12v in a 1/2" hammer drill. Very small and lightweight and has more power than the big name drills of 10years ago. But for what she wants, their cheaper 3/8" drill would be perfect and will last a long time.
