I would recommend the Benchmade Barrage. I own one and it is hands down the most fun assisted opener i've gotten to play with. It snaps open with a really loud snap and its pretty strong. Out of all my knife-appreciating friends, it gets the most attention when opened. I'm not going to lie, I also feel badass when I snap it open. The Mini-Barrage is also just as awesome but a bit smaller and cheaper, but if your like me and you have long fingers, the full size feels much better.
Price wise, I'm not sure if you can find it online for 100, but I found mine for 112 dollars at a brick and mortar store, so I'm pretty sure you'll find one online for the right price.
Also, a lot of people complain about the handles feeling plasticy and cheap, but they feel fine to me, and are really durable. I've been carrying mine daily for 4 months or so now, and there aren't any real dings or marks. Thing is, I also don't use it roughly or abuse it, so you might want to take that into consideration.
Finally, no wiggle or blade play in mine, combined with full skeletonized liners and manual safety for both open and closed seems like a pretty good deal to me.
Good luck with finding your new knife, hope you have fun with it.
