Well that box of calculators i got for $40 off of Facebook was far more lucrative than I thought.
Two models were actually one step up than what I had expected based on the Facebook photos.
I was only really after the hp 48g, it goes for $125 so just that alone would have been fine. It turned out to be the 48gx, a lot more desirable acceptable Condition was like $200. This had manuals and is in really good shape.
Prices for the 6 hp calculators listed on Amazon totaled about $750!?! Two other calculators are in the $15 each range on eBay (a Casio graphing calculator and a Sharp 2 line scientific)
