Keyboard Advice

So my keyboard at home died this weekend, it started typing q's and z's instead of my shift keys, and Tab and Caps Lock each do both. I've been thinking about purchasing one. I don't do a ton of computer gaming and most of it now is with a controller and I can snag a free regular keyboard from home just to have one. But I've been thinking about purchasing one for work, have any of y'all purchased a personal keyboard for work to ditch the basic all-in-one type that come with PCs? Have been looking into the mechanical ones, but I'm curious if you think it's actually worth the price for it when it's for typing not gaming. Thanks!
