If a keyboard sits on a very dusty garage shelf for 20 years with no cover, sometimes dust works its way inside the switches; cleaning that out is a lot more complicated, requiring desoldering and disassembling all of the switches. Don’t do this to your keyboard, and watch out for the condition of decades-old used keyboards.

Personally I like very loud clicky keyboards, like the IBM model F or anything with clicky Alps SKCM or SKCP switches (from the 1980s–early 90s).
If you can find one in good condition and don’t mind an adapter, I quite like the Apple Extended Keyboard II from ~1990 which is reasonably quiet (likely louder than the Amazon board; if you want to further reduce the sound you could open up the case and fill the empty spaces inside with some kind of padding – I know people who have successfully damped sound with sheets of drawer liner or felt).
Tactile Cherry MX switches (or any of the many MX clones) with added o-rings or other padding are reasonably quiet. I’m not really the person to ask though. Again, filling empty spaces inside the case can do a lot to damp the sound.
When it comes to the life span of the keyboard, how easy are they to clean?
With this Amazon one, I seriously spend about 30 seconds every 2 weeks wiping it down with a small towel and it's as good as new in terms of cleanliness.
I'm not a neat freak but I do know that build up of whatever can definitely play a role in how the keyboard feels over time and full size keys tend to collect a lot more debris over time.
Also if you don't mind, what would be 2-3 recommendations in the $50 range where quietness and overall "this feels great to type on" are the biggest goals?
