I like the higher end Kershaw's and the ZT's. The Random Task II (discontinued) is on sale most places and a steal for less than 50 bucks. You can't go wrong with Blurs either. Another neato Kershaw is the Ripcord. It's unusual as it's a OTF knife (also discontinued).
If I were you, I'd also try and get a G-10 Lee while you still can. They've been DC'd and are fantastic little knives - IMHO, the best leek handle out there. The blade is premium S30V on those. The Random Leek is also DC'd but still available. Of course these are just some of my Kershaw fav's. Everybody has their taste, but I also like the *hunt* for knives that are getting harder to find.
There are a couple ZT's on good sale right now too! The 0121 (dc'd) is a STEAL right now. Just have to look around as I don't think we're allowed to post vendors here unless they're paying vendors. I'm not sure if they are or not. Anyways, just do some searching and you'll find the deals.
