I agree that there is no such thing as a price-point or specific MC that beats out any MM/MI cartridge; it is really a matter of taste. There are some who would say that a Decca London will beat out any cartridge of any type for example. But, there are certainly lower priced MCs that do, to me sound quite good for their price and are worth checking out. As someone mentioned above, the Ortofon Quintet Blue is a bargain, particularly if one is looking for a warm cartridge along the lines of a Koetsu, but at a fraction of the price.
For a completely different sound (or detailed, less warm sound) an at a much higher price, I like the Lyra Delos.
