This is a tough game, but I'd say my Princeton Tec EOS and White Box stove both come under the wire together at $50, and have gotten hard use over the last few years.
For the honorable mentions:
Mora knives, mil-surp Trangia stove, Stratus Trail Stove, Emberlit Stove, Primus Litech kettle, my wonderful collection of heavy duty 100% wool commando sweaters from various countries, and even my little UCI candle which isn't
needed, but I love it anyway.
