the Bradford Guardian3 is within $10 of your top line, but it does come with M390 steel and is a better slicer than almost any other knife its size I've owned. You should be able to find one under $150 on the exchange.
The Guardian 3 is available for a lot less in ordinary steel (N6__). Bark River has a wide range of small models. The Bravo Necker 2 has a thin slicy blade, about 7" total length.
