Good Brands for Front Pannier Rack on Suspension Forks
Get the rack first or get them together.  You need the panniers to attach solid.  Not all racks have the same places to attach.  I have Surly Ortleib combo but that is like $200.

An over the top design like this gives you more storage.  And you could lash some stuff and maybe skip the panniers. Those two little tabs on the bottom are nice for lashing.

Give yourself an hour or two to install.  Lots spacers and lots of positions. 

And on a fork look for threads at the bottom of the fork and mid fork. That bike also has threads on the inside for another attachment point but don't worry about that.  Go to the gallery.
