Quoted from boustrophedonic:Maybe "trades" refers to the wife and not the machine?
Upgrade to a newer one ( wife) ??? But New ones are always way more money. Best to stick with your old one.
At least you might have an idea what issues might need to be addressed - even if better parts aren't available or there are mysterious circuitry problems the that can't be solved. You at least know what you have. Or think you do anyway.
I don't think trades of that nature would work well. Always better to sell outright.
