The conversion is acutally twin-fuel: the engine burns mostly diesel with 20-25% LPG. So it doesn't save you much money. But the proponents claim that it eliminates soot from the exhaust, which would be a bonus when coked-up diesel particulate filters cost a motser. When diesels are now a pollution problem, seems worth considering.
I have found a few scientific papers on blending diesel with short alkanes (methane propane pentane) and I doubt it would reduce soot to zero.
Who has an LPG diesel? What is your opinion?

You'll never eliminate the soot from the exhaust other than by not starting it but adding LPG might reduce it a bit (but never down as low as a petrol engine). As I understand it, not having a diesel (and would never consider one either), the LPG addition will give extra power or better economy depending on how you drive it. An improvement in emissions is regarded as an added bonus not the reason for the conversion.
