Looked and looked for that same spinner handle, but couldn't find it (main reason, CAT calls it a "Driver Socket")--$18.20 here. Looks like much of what you have is basically my list (they have the six-piece screwdriver set in-stock at my store) except for a couple pairs of pliers.
Looks like I've lost my Snap-On pocket prybar for good. It's being replaced with the Lang set, as the Snap-On dealer's schedule at the shop by me and mine don't match up that often. However, at under $5, you really can't beat the 6V-9124 as a light duty prybar and pocket screwdriver. I can buy four of them for slightly more than just one Snap-On. Kind of wish Williams and CAT would have a rebrand of the Snap-On mini prybar. The clips on most others simply don't last. Gotta warranty my Macs--they both pull out constantly even after repeated gluings. I presume the CAT is similar to Snap-On's.
I was able to find the "driver socket" because someone posted a picture of it earlier in the thread and I got the PN from it; never knew it existed before this thread. For whatever reason, there is no Williams version of this with the same square hard handle. Yes, there is a Williams version of this tool, but not with this handle, which is what I wanted.
The tiny screwdrivers were ~$3 each for me

. I typically use screwdrivers like this for light prying duties, but I picked up the small Mac pry bars, so I might not use these much for prying. I'm a DIYer and don't carry them in my pocket, so I removed the Mac clips. And yes, they come off easily.
I'm in East TN, so I'm surprised the prices are so different if you're in VA. Obviously, your dealer isn't as nice as mine LOL. However, the local Toyota dealer marks up parts prices at like 25% over list, so I guess your Cat place is similar.
I also have the Lang pry bars and like them- good proportions. Much more HD than the Mac, but I have most of the mini pry bar selection and use almost all of them; I use Mac the most, the Mayhew the least.
I debated getting the basic Cat three-piece plier set as posted earlier in the thread, but I have so many pliers that I actually exercised some self-control for once. But I'll probably give in and buy them in the future

. Not because I need more pliers, but I don't have any SO pliers, so....
