I need a folder for SERE school

Anyone have any recommendations? I would like something with a blade between 3.5 to 4.5 inches, liner lock, thumb stud and flipper, no assisted/spring opening, no serrations, and under $100. I've heard about the Al Mar sere but people say they're not as good anymore since production moved to China. Any expert advice? This will be a more secondary knife since I'll have a fixed blade already. pic for attention
