Check eBay ! You should be able to get a used Craftsman 1/4" set for under $20 !
Craftsman 18 pc 3/8 and 1/4 Metric Socket Set (no drivers) $20 I added a couple of socket to my 1/4" set which now goes 5.5mm to 15mm.
IMHO 1/4" are a waste of money. What you want is ...
- 1/4" screwdriver/driver handle/extension/spinner with a female 1/4" socket in the top (Craftsman 43371)
- a 1/4" breaker bar
- a short 3/8" ratchet
DO NOT BUY 12 POINT 1/4" SOCKETS. They will round of the nut/bolt heads.
I do NOT own any 1/4" deep socket. In 55 years of DIY twisting wrenches and sockets, I have never needed one or my 3/8" deep cover what I need !
If you can not find a set with a box, buy the cheap, plastic socket rails from HF. Cut to length.
