But in a MM cartridge the body is 5% of the cost. Seems to me they could just wire both channels to the horizontal and call it a day.

Do you mean the cost for the manufacturer or for a consumer?
In terms of the market price for a consumer I think it's the other way around, the MC body is useless without stylus/cantilever and cost almost nothing, while the MM cartridge body is expensive because we can manually insert the stylus in 3 seconds to return it back to life. So i think it can be easily 30-50% of the total cost, but the stylus is the most expensive part of MM/MI, definitely.
I don't disagree with anything HDM wrote above. That's pretty much what I said too. But I would not go overboard to say that mono cartridges derived by bridging stereo channels are to be dismissed out of hand. First of all, that would drastically limit one's choice, as the market is quite thin on "true mono" cartridges. And second because I have had a great result just using a mono switch on either of two preamplifiers that I own that provide for same. The mono switch acts further up the chain to bridge the stereo input, so it is subject to the same caveats as are bridged mono cartridges. Yet it works dramatically well to improve the mono LP experience. Lower noise, better high frequencies, etc.
And finally, the manufacturers have made it very difficult for buyers to figure out how they have constructed their mono cartridge offerings. If you want to see double talk that rivals only the drivel of politicians, go to one of those websites and read about mono cartridges.
Sorry, I forgot one thing. Chakster, the way you have hooked up your Grace to your stereo system could cause a degradation of performance, because each channel of your stereo phono stage is now seeing the output impedance of the cartridge in parallel with the input impedance of the other channel. But since you are probably running a 47K resistor on each channel as cartridge load, which gives a fairly high impedance in parallel with a much lower one at the cartridge, I am guessing the effect is not too terrible for performance. Conversely, the cartridge is driving the two channels in parallel.
