So you buy a nice two shelf bookcase but it’s wobbly and you know it won’t hold much. I’ve recently gotten one and my solution was to put L-brackets on it. After installing about 8 of these brackets at the cojoining parts of the shelving, it is now completely stable and ready for use.
I think that can come after because for some people, a powered drill is a bit of an expense they can’t afford. I had to go without a good powered drill of my own for about a year after I got my first home. I borrowed a lot of things back then. I did have a drill but it was a 1950s black and decker wired one that was on its last legs. It took me about two / three years before I got my first brand new drill and it was wired because it was cheap. Wired drills are cheaper, last longer - they are less convenient but at least they get the job done. Then it took me about five years later before I got a good cordless one for about $200. Then it took me about ten years later when I got a lithium battery powered Dewalt impact driver and drill set and its all I ever use now.
You can start off with a cheap battery powered drill but honestly, I’d just wait until you can afford a $200-$300 impact/drill set (they usually go on sale at some point) and that set will last you years or decades of use. If you buy a cheap one (like I did), the battery will die prematurely in a year and you’ll end up buying another one … do this three or four times over four years and the cost would have been saved if you had just bought one good powered drill to begin with.
Ask me how I know because the first powered drills I bought were cheap $100 specials - they were good but the batteries never last … even just sitting eventually just drains the batteries and slowly kills them.
I’ve had a $60 Ryobi drill for 10+ years. The battery and the drill work just fine. For basic maintenance, I would rate a cordless drill in my top 5 tools - up there with a hammer and tape measure.
