Jay, I know you want to save a few bucks but you can buy a brand new Touchstone charger through a dozen different stores for not much money. Amazon just had it on sale for $33 + free shipping about 2 weeks ago. Office Depot had a fire sale at limited locations for $7 dollars also 2 weeks ago.
I'd love a touchstone as well -- however they seem to be getting more and more rare.
I do agree with the advice - saving a few bucks (while good) can also be counter productive in the long run. I wish I'd have known about the 7 dollar fire sale via office depot.
