With used keyboards so cheap, and internal cords and parts so very hard to find, there are few who are repairing keyboards or offering the parts. A used one that has been treated well is probably your best bet.
If you are adventurous, you could buy a used keyboard with a different problem -- say, missing keycaps -- and harvest the needed parts from that one (or the reverse).
Thank you Martin. THIS is the answer I needed to know. I am as green as they come...not cheap. Buying a new keyboard is not the problem...I would have rather recycled mine with a new wire.
Grant, also...thanks for that - great idea...buying a cheap old used one with missing keys and use the ones from mine. Brilliant. I may just go that rout. RECYCLE EVERYBODY!!!
Thank you all guys for your help.
