I know I'm a scrounger, and that I tend to be cheap and not spend money where I don't have to.
But you mean to tell me you guys don't have a box full of keyboards in a closet someplace?
I have at least 6 good ones left that I salvaged from curbside "clean up" week 6 or 7 years ago.
Along with a couple of more modern "USB" type that I don't like as well.
Also if I tended to spill liquids on it often I think I'd get one of those silicone keyboards that you can roll up.
Give it a rinse, hang it up to dry for a couple hours and plug it back in.
Virtually indestructible,Can operate in shallow water, dusty, acidic, alkaline and damp environments. Robust silicone rubber design. Washable with water, alcohol or disinfectants
