well, in the context of this thread, the op is talking about a "complete" set. That's why i, personally, am not discussing "the basics".
The 299 piece set is currently $329.99, with no additional discount/coupons (and those discounts/coupons come around with pretty decent frequency). It's all sockets, no filler.
Paying that, you're at roughly $1.10/socket.
In fact, just checking, there's a $20 of $150 storewide coupon (code 9700080954578349) on the sears.com site that you can load, making that set $309.99, so ~$1.04/socket, and that also would earn, at least for my account, $33.10 to redeem on a future order. There's also the free shipping, on top of all of that.
How is that not a value choice?
From a "complete" standpoint, at least in 1/4", 3/8" and 1/2" drive, you can't really buy a set more complete for the price. The only thing that set is notably missing is 1/4" metric 12pt stuff (it's got 6pt and 12pt sae, and 6pt metric - i supplemented mine with carlyle in that respect).
Given op's statement:
Can you name another socket set that fits that bill, for anywhere near that price?
Op did mention a concern about the craftsman warranty. I honestly believe sbd will continue to honor the warranty, but even if they don't, it's not likely you'll bust one of these sockets, but if you do, you paid ~$1 for one, so if you have to replace it on your own dime, you're still ahead of the game.
