Okay, granted that suspension forks add weight, increase maintenance costs, and rob power. However, it's a 2.4 mile commute over varied terrain. Disc brakes, wide tire clearance, and (hopefully) stronger wheels are the features I want. I'm willing to pay the weight and performance penalties.

Using Trek as an example, a 3500 mtb w/discs lists for $479.99, their cheapest hybrid w/discs is the PDX which lists for $639.99.
