The MM2 (standard 1.5" dia. steel rollers) is $160 + shipping at Farmhouse Brewing. This price includes the base and standard hopper, and is currently in stock (according to their website). I bought mine from them a couple months back and the price with shipping was $172.

I used a BC at my LHBS before purchasing my MM2 and it was a total POS. Flimsy hopper, rollers constantly losing traction, and the gap setting would not stay put. Really soured me on the BC. Of course, the thing probably had a gazillion pounds of grain run through it over the years, but I wasn't all too impressed, which is why I opted for the Monster. I couldn't be happier. It's a beast!!!
Doesn't look like the base and hopper are included in that price according to the description. So what are we talkin, ~$130 for the BC or ~$250 for the MM? Pretty big price difference. Sounds like the quality is superior though from feedback on this thread.
