You just can't go wrong with a Leatherman, you can check out a lot of their models in places like Walmart or Bass Pro Shops (if you have one near). Their website is also very user-friendly and you can browose through most of their line up. However if comfort an weight are important to you, you should really check them out first hand. As Dantor mentioned, Xmas season is coming and they usually offer some gift packages especially in the aforementioned strores. For $80 or less you can get something really good.
If you are willing to spend maybe ten more bucks, check out Victorinox offerings, especially the SwissTool Spirit X and Spirit Road Tour edition, they're just great tools for the money and use Vitorinox propietary steel.
