They have so many model variations, constantly changing, and many model numbers may be made for only one retail chain, so it's hard to know which ones are good and which ones are better, and making it difficult to comparison shop directly. Honest, for household use, almost any drill from a reliable company will be sufficient.
You might get a 'feel' for the differences by visiting a home improvement store in person. The very cheapest drills (Black and Decker, etc.) will feel obviously Chincy. Some will have a more comfortable grip too.
Just from glancing at that stores online selection, I'd buy the DWD110K or DWD112.
I have purchased many DeWalt tools over the years, and never had to replace one yet. Every single one is still kicking strong. :thumbup:
I wouldn't be concerned about that with an at least mid-range brand like DeWalt, Makita, Bosch, etc.

If you really want to spend more money to feel like you're getting a better tool, there's nothing wrong with Makita. Our Helpful Friendly hardware store stocks a full selection of Makita tools as well as DeWalt, and their prices are competitive with ordering online. Maybe stop by and see for yourself if you have a preference in grip, weight, or features. Heck, maybe you'll just like the blue better than yellow.

Some folks will undoubtedly say the extra $15-$20 for Makita is worth it. There's no wrong choice, it's only fifteen dollars, and both brands are well within your stated budget.
