I'm kind of a guy stuff junk collector. I have a dozen of knife sheaths, half of them are nylon and half leather and I keep saying I'm going to fill them with knives.
I have about a dozen of solid state amplifiers and one tube amplifier.
1 working laptop, 2 semi-working laptop and two desktops.
Half dozen scientific calculators although I don't know why.
Tool sets. I used to have a neighbor which took many donations from me of individual tools.
I unfortunately live near a GoodWill outlet store. 'Outlet' being the keyword. Overpriced items from the normal regional GW stores are sold by the pound really cheap. Today, I found a large (about 40 pieces) Ryobi drill bit set, a separate (20 pieces) driver bit set, several loose tools and a N300 dual band router - paid about $5. Little more than I usually spend. The tube amplifier (Heathkit SA-2) I bought from there awhile back cost less than that.
