Is this for a home cook or a professional cook?
If you are looking for a professional cook, then I would suggest something from the Victorinox Fibrox series. You are getting your money's worth and it's NSF certified. The Rosewood series (posted by Old Navy) is a great set for home, but not great for a commercial kitchen (due to the wood handle...that's a no-no in many kitchens due to the ease of bacterial growth on wood handles).
It may be difficult to find a full kitchen set for $100 and under, so a partial set (like the 3-piece set above) may be your best bet...Another idea, may be getting a single Mid-range Chef knife (Shun was the go-to for mid-range kitchen knives years ago, but I'm not sure what's hot anymore for that segment) and getting it engraved for them.
