I don't know what's available at your local stores (though the internet is always there) but my wife and I have had a lot of fun with buckling, fur lined leather cuffs. They are really gentle on her wrists/ankles, but still restrain quite thoroughly, and they have D-rings for easy attachment. Add a half dozen carabiners to your collection of toys and you can go a looonng way with a set of wrist/ankle restraints.

Alternatively if you want to go with leather but like the metal look, I have seen several variations on stainless steel sheet metal riveted to buckling/locking leather underpinnings. I have never used those so don't know how they hold up, but they look drop dead sexy.

As far as classic-style cuffs, I have a few different pairs. I have some very heavy gauge, hinged cuffs. They are quite thoroughly effective, but can often be too constrictive as they hold the hands/arms in too fixed a position and don't allow enough movement/flexibility the way cuffs with a chain or wrist restraints would. They're also pretty rough on the skin as they re pretty heavy duty.

I also have some "cheap" trick-cuffs, with a release lever on them which obviates the need for a key (though I still have a key for them.) They actually hold up quite well under use, and they provide a lot of confidence in terms of safety/consensuality, as my wife (and my other partners before her) were, actually, really restrained, but could in an emergency situation fiddle with them enough to get them off. In several years of using them with various partners I have never had anyone even -attempt- to slip the lock, though perhaps your scenes are different

The trick-cuffs (and the leather/fur restraints as well for that matter) are also very nice post-scene, as they can be released quickly and easily without any fumbling around for a key when all you (both) want to do is lie down and drink a couple liters of water
