Does anyone know if there is a big difference between the MB1, MB2, and MB3? Preference which is better? Has it improved since MB1 or do people feel MB1 or MB2 are far more superior than MB3?

I have yet to try any, but my B&M told me they are able to order the MB3 for:

Robusto $9.00
Dbl Robusto $11.00
Churchill $11.00
Torpedo $12.00

Are these prices pretty decent or over inflated?
