I was in the same boat not long ago, I've been using a mix of ancient Craftsman, Proto, Williams, etc. forever. Decided since I'm getting into the diesel field I'd need some new stuff (since I had almost nothing in metric) and wanted all the same brand. Even with my school discount, Snap-On was too rich for me after 2 orders (kept my ratchets and wrenches, sold the sockets).
I've since gone with Williams USA for sockets. They are identical to Snap-On, which makes it so any gaps can be filled with Snap-On singles (OCD again filling socket trays) and are 1/4 the price.
There are still misc things I don't use enough to justify the cost. For those I've been filling with Kobalt USA stuff from Cripe (3/4" Drive sockets, BIG combo wrenches, Torx sockets, Allen sockets), Some Kobalt Taiwan (flex-sockets on sale), Ingersoll Rand impact sockets (with some Armstrong and Sunex fillers), and some misc Gearwrench stuff. The OCD has calmed down quite a bit just in looking at the price difference.
I do have a socket and tool list I built with prices and links I could message to you if interested. Might help you out, I know it has the other guys in the shop.
