stay away from Deore Mechanicals, they just don't work. They don't squeal and they have good modulation but they really don't stop you! You can grab a handful of lever and still not really stop.
The Hydraulic Deores are worlds apart, much better than Hope Minis *(cheaper too)but heavier and don't look so "trick". Check out 2002 Orange who are using the cheaper version of the Deore Hydraulic on loads of their bikes.
