Any advice on power supplies for these dinosaurs?

About 6mos ago I bought a used series 1 to scavenge its power supply and it just died. (ticking power supply and black screen). So now I have my dead units plus one for parts. I would like to get one running.

Because of MS I don't solder anymore. Me repairing them isn't an option.
I could look for another used unit but it is a gamble on how long it will last.

Is there anyone who repairs power supplies?
I don't know if I could talk my husband into letting me get one fixed if it costs too much though.
