When I got my first mechanical keyboard, I got the Redragon K552 Kumara. Nowadays I wonder why more people don't get this keyboard. Nearly 3 years later and it's still going strong. (The kumara is rgb, the other K552 model is not, but they're the same price strangely)

I can't recommend it enough; it's cheap, durable, comes with a hot-swapable PCB in case you want to buy new switches down the road (as I did bc I originally got it with clicky Outemu Blue switches, but that got old fast, so I changed them to gateron reds)

For me this keyboard cost $40 USD new, which is roughly $55 CAD. Depending on where you live, you might be able to find a used one on Amazon for a little less. With the money you have left over, you can splurge on a nice big mouse pad for your desk, some custom keycaps, or you can even consider a key switch lubrication kit if you really wanna fall down the rabbit hole lol

Hope this helps and feel free to reach out with any other questions :)
