Most of mine are Snap On too from my workshop days.. Very hard to justify the cost now if they aren't to be used every day.
If you avoid the obvious very cheap and nasty stuff I think most of the mid range kit will serve you fine.
Agree that a versatile 3/8 drive will get most use and maybe a couple of 1/2 drive sockets and bar for the bigger jobs.
Elora, Williams, Kamasa, Blue Point, Britool.. I've got them all in addition to the Snap On stuff and they are all fine.
