There are a lot of good choices for you, and going a bit under or over 100 you can tailor your choices by figuring out what you want; for example, g10 scales, a certain lock, what size blade, style of clip... Under 100, if you like the endura, I'd have to suggest a delica; pretty much a 3 inch endura and tough as nails. As mentioned above, the paramilitary 2 is a great knife (between 3 and 4 inch blade), and might be worth a little extra money if you dig the style, lock, and steel. They are great knives. The other knife I would suggest is the sage1. I love the sage 2 because for me, the wire clip is great and it is just the right size to be small but useful. The 2 is a bit more, but you might be able to find a sage 1 (3 inch )around 100. s30v blade, liner lock, and if you don't have any Taiwan made Spyderco's, the fit and finish (in my experience) is really great and worth trying. If you want an assisted knife, I paid under 100 for a Kershaw shallot in damascus. Don't have any ZT knives yet, but if you can stretch to one and want something solid, that seems like a good choice as well. Good luck picking one..
