I hear that the yoyoking ghost bi-metal is pretty decent. Vosun makes a good bi-metal for a wee bit more (worth it though). I also routinely find myself pulling out one of my first throws I got on Amazon that gets no love for some reason, the Spintastics Space Monkey (https://www.amazon.com/Spintastics-Professional-Bimetal-Aluminum-Bearing/dp/B073RQTQY7/). It is a great throw for the price in my experience. Also, yoyofactory makes the Bi-Metal which is lower in price and a super throw (again more than you want to spend but quite worth it if you can find a deal or something).
