Never bought a whole set of them, but i have quite a few SK sae 6pt long pattern combination wrenches that have more than paid for themselves, think you can get a 13pc metric set for about $100 or so
Snap-on. Lol. Not affordable though. Mine never let me down. If ur looking for affordable ones. Find an american set of craftsman wrenches dont buy the new chinese ****.
I have a mix of SK and Craftsman. The SK are double ended different sizes which is handy as if I need an open end I would just use a standard 12pt combo. Been happy with both. The SK's I think are a bit nicer, but the craftsman are not far behind IMHO.
