fix the old stuff.
while you are fixing it, you can disable all the pre-smart, "features", further fixing it
impact driver, and a few wrenches, if it's realy
broken, then keep going till its easy to tote pieces, and go find a used one someone is just replacing in an "upgrade"
older heavy duty commercial stuff is sought after now....it was designed to be fixed.
personaly, I can fix, or modify,most stuff, and scratch build any imaginable simple machine, mostly for shop or agricultural use, but venture into marine and aviation parts and systems.
a lot of (older) domestic and comercial stuff can be figured out just useing visual diagnosis and following the logic of the circuits, which is often usefull in detrmining that the broken part is a "feature" and can just be bypassed, essentialy backdating the applience to an even earlier itteration, which then goes ahead and washes clothes, which you know are now clean, because the machine STOPPED making noise, rather than finishing with a flourish of beeping, or buzzing
