Ka-Bar Dozier (multiple colors too!)
CRKT Drifter
Kershaw Scramp
All of those are just at $20 or even slightly under online. All very nice knives. The drifter is very beautiful and the scramp a great EDC.
I just recently got an orange Ka-Bar Dozier and I have to say it's an incredibly functional knife. Minimal parts, simple mechanism, great blade shape, light, bright orange, even the clip is very good. It might feel cheap to someone not used to knives since it's so light, but for someone with a collection of 20+ spydercos, benchmades, etc. I have to say it's a great example of knife engineering because it perfectly fulfills what it sets out to do and doesn't aspire to do more. I could easily see myself buying 3-4 more to keep in various places.
