Jandd Extreme Front Rack is prerty much a rear rack designed to mount on the front using p clamps.
Old Man Mountain also makes racks that mount with clamps.
I recently bought a Nitto Big Front Rack from Rivendell:

Pricey and not the lightest thing invented, but it's beautiful (nickel plated) and super strong. It also mounts with p clamps (included). The panniers mount mid-level.

I have no handling problems. In fact, I have only ever toured with a front rack with a platform and mid-mount panniers. My previous set of racks were from Bob Beckman. Unfortunately, they were stolen along with the bike they were attached to and wait time for a new set was too long.
