Yamaha DTXpress/DTXplorer/DTXtreme

Hey, OGD,

I don't want to jump the gun, but the MR-100DR (100 watt sub) at $600 
and the MR-50DR at $300 (50 watt sub) look like just what the doctor 
ordered for people who need modest amplification, and at a price that 
puts Roland to shame. Well done, Yamaha. All we need now is a review 
of their performance.
