Pretty sure any USA Allen, KD, etc are the same as Craftsman just a little different style-wise. Didn't they all come out of the same factory in Texas?
Allen, KD, and Armstrong are gone, as In defunct. There are certainly some deals on discontinued products from them out there from liquidators, but liquidators don’t set market prices for tools. They are essentially scavengers, clearing out discontinued product, for the most part.

I just checked, and that 70 piece Craftsman set is about $74 at Lowe’s, not on sale. It probably cost no more than $50 on sale.
A cursory search shows a 19 piece Wright set going for $264. I didn’t look up SnapOn, but I recall about $370 for a set of them (from memory).
Tecton lists their set at $100, and their is a Crescent set at about the same as the Craftsman with five minutes of searching
At those prices I wouldn’t expect similar “quality”, whatever that is over the several hundred dollar price swing.
Not worthy of a rant, anyway.
