Personally I'm not a fan of Spyderco(I just don't like the way they feel) I had been looking at some Benchmade knives but I haven't found one that quite did it for me yet, as for price range its going to be a birthday present for myself, and that isn't until July so I have plenty of time to save up for almost anything, which is why I didn't address the matter of price earlier
I'm a big fan of flippers myself. Titanium doesn't do much for me, but most flippers and high end knives use it. The "grail" for those new to high end knives is usually a Strider, CRK, or Hinderer. I've owned a Strider SnG, but sold it when I needed funds. Since then, I've always found something else that draws me away from those three brands. A year ago I had over 35 folders. Now I have 11. My next knife will be a custom with specific design elements I want. That won't be until after July, as all my funds are going towards my wedding.
If you want something that is a little off the beaten path, but is still reasonable ($300 and under), I have a few recommendations for you.
Three Sisters Forge Beast--I love mine, Ti, S35VN.
Brous Blades--LNIB can be found at reasonable prices. I have the Bionic myself. Their folders have flippers and bearing pivots.
Southern Grind Bad Monkey--Premium materials (Carbon Fiber or G10 over Ti, available with or without the Emerson Wave.
Kizer--My Ki423 is currently my favorite knife in my stable. Unique Ti scale design, CPM-S35VN steel with flipper and bearing pivot
LionSteel/DPx
There are many others of course.
