I like knives that are affordable but are well built.
Back when I needed a more substantial blade, the RAT 1 met my needs pretty well. The last few years I've been happy with a basic Delica however the prices keep going up and for a VG10 blade and FRN handles I wouldn't spend what they're asking now.
Recently picked a CJRB Pyrite as my intro to button locks and it's very well put together and easy opening for those who "fidget" with their knives. Steel is AR-RPM (supposedly proprietary) and price on Amazon was $50. Haven't yet decided what I think about the button lock though.

The last one I snagged is the SOG Terminus XR in S35VN, sliding bar lock, carbon fiber /G10 handles. It has both a flipper and thumb studs and for $75, I think it was a good buy. It does have soe design issues I don't like: flipper is needlessly sharp and the deep carry clip lets my jean pocket slip up and over the rear of the handle which makes it near impossible to pull it out of my pocket using my usual pinch grip. I was able to address both issues with some slight modification.
