Pullers
It either takes a whole lot of money, or a lot of time, and a much smaller amount of money (which was my case) to accumulate a wide selection of quality pullers. Now doing it on the cheap like I have I do not have quite the extensive range of pullers I see in your collection, though I do have a good selection for a home shop guy that has never worked in the trades or as a paid wrench so the cost of $ quality pullers like a few of those shown I have never been able to add.
My pullers have all been bought on the cheap, or at least semi reasonable. I never needed the puller I bought when I bought every one of them. I bought them used knowing it might be years before I use them. If you buy them cheap enough you can afford to have them for years before using them due to their great cost (the quality ones) I always have my eyes peeled for quality pullers on the cheap and will buy them in a heartbeat when I find them cheap enough. The good ones are few and far between used (unless you are Phil) so I grab them quick when they show up!
I like all of your pullers!
Most of my tools were bought with a lot of time and gas and little money. My Snap on standard wrench set from 1/4" to 1-5/8" was acquired using the Johnny Cash method. I bought the 1-1/2" , 1-1-7/16" and 1-5/16" new from Snap on the rest were flea markets yard sales and trading. Same for the pullers
If I actually worked in the trades there have been several Snap-on sets that were dirt cheap $100-150 dollar neighborhood that I would have added through the years if I had wrenched for a living or was someone whose living depends on my tools, but when found it was after my carefree single tool buying days with a wife and four kids so sadly, those great bargains just did not fit or my supply of pullers might have been almost twice what it is today with no more than maybe $3-4 hundred outlay for trade quality USA made sets. It was tough to pass on those bargains, but I cannot complain, I have been lucky to assemble what I have on the cheap.
A lot of time, gas and money is the smartest way to buy tools if one can in my opinion, though sometimes a guy will end up with some mixed sets of quality sockets in doing so. For example, my 1/2" chrome swivels are a mixed brand set that took years to acquire.
Sounds like your and mu approach to buying tools is very similar though.
My experience buying pullers used has been that unless it says Snap-on or Mac or Matco on it all the rest of the quality brands like Proto, OTC, Blackhawk and the rest fly under the radar in many pawn shops and second hand. Unless the seller is shrewd and tool savvy pullers are often undervalued and even among tool buyers, often the bargain is underappreciated or unrecognized. Especially for older names like Hinsdale or Plomb. (Although Plomb bargains are not as plentiful as they once were)
You just have to pass on the Hobo Freight stuff and only settle for the good stuff! (A few tools I refuse to accept cheaper imports and the first on that list has always been pullers. Way too much opportunity for injury when you start exerting hundreds or thousands of pounds of force to risk that on cheap tools)
