I have a lot of tools, some very expensive, but my favorite is this set of SnapOn flare nut/open end wrenches. They are kind of mis-matched because I collected them on eBay over time as I found good deals. After a career of using lesser flare nut wrenches, the SnapOns are fantastic. Fittings that other brands would strip, the SnapOn loosens up without damage.
My favorite 1/4" drive ratchet. It's an antique, but I like it better than my new SnapOn Dual 80s. This was a broken swap meet find that I paid a buck for. Then I finally found a rebuild kit for it. I'm into it for about 10 bucks total. It's somewhere in the 60s era vintage and works smoother than any ratchet I've ever used.
And I'm currently collecting SnapOn "hi performance" metric deep offset box end wrenches. These are not very common so the collection is slow going. I'll get there eventually.
