B3 vs M3 Hammond Organ

So i pulled the rotating Leslie out of an organ and i want to be able to hook it up with my guitar amps. It has an 8" speaker thats 35 watts, i think. Anyone know were i could get a hold of something that would convert a large signal down to something like that? I also need a power supply and a way to control the 2 speeds that it can run at.

What's the deal with Hammond Organs in general and the B3 in particular. Why are they revered as they are? What's the difference between the B3 and the M3. If you had an opportunity to pick up either at a good price, would you? Why?



I ask because I've been hearing a lot about these lately and I'm just wondering what's up with'em.



Thanks
