Don't fall for the silly marketing associated with cycling tool brands, and terms like "shop quality"
There are companies, like Bondhus, that supply aerospace and automotive factories (I've seen them there). A set of their t-handle hexes start around $50 USD. If it's good enough for the people that put together the planes your fly on, they'll be more than fine for your open mold bike, or any high end bike.
Just look for a set that is comfortable, is long enough to reach the things you need (like water bottle cage bolts), has a lifetime warranty, and preferably get them from a local store where you can deal with any warranty issues that come up (should be rare in my experience). I would spend around $30-60 USD for a set, and use the savings elsewhere.
