Small town rural areas. Garbage sales and estate auctions are your best bet for value. Seems I come across the best deals when I am not really looking. My place looks like Sanford and Sons at times. Too much. I don't need to find any more deals.
Alladin lanterns are my soft spot. I have too many. Very little invested in them but their value at the internet prices is amazing.
Next would have to be Coleman lanterns. 8 working antique models. A few junkers. Modern junkers too. Use them for parts. Have 3 propane working lanterns than I have less than $10 in the lot. Have a couple of 288's that I use regularly. A northstar I put on the bottle when in need.
As far as tools go I have some things I don't even know what they are. Have most of my great grandfather's blacksmith tools. Have other things I have picked up through the years. Scales, pulleys, wrenches, home made crap too. Have a few dozen double trees. Several old breaking plows.
It is amazing what old timers just give me. I hate to say no. They are cleaning out old barns and they give things to me because I restore so much old junk.
