Got this response from Jack Sweeney at Bikecommuters...
John...unfortunately, you can't have it both ways: you can either have GOOD fenders, or you can have "easy on/easy off" fenders.
For example, the SKS Race Blade -- they go on and off very quickly, but they don't provide enough coverage to really keep you and your bike clean and dry. Same goes with the seatpost-clamping rear fenders. Same with the clip-on front mini-fender that goes on the downtube.
I've tried a couple modern brands of fenders, notably the Zefal Cafe models and the Planet Bike full-coverage fenders with integral mudguards. The Planet Bike ones are substantially better (better hardware, more versatile). One trick some folks use to make the fenders go on and off easier is to thread longer mounting bolts "inside out" (from the inside of the fork/dropout bosses toward the outside of the frame) and using metric wingnuts to attach the stays and struts. Still, it's not a 30 second removal process!
If you go for really blingy, indestructible fenders, I heartily recommend either Honjo or Giles Berthoud fenders. Honjos come in fluted, smooth or hammered-finish aluminum, while the Berthoud ones come in stainless steel. The mounting hardware and struts are without peer, and either brand is so gorgeous that you won't want to take them off!
Either Peter White Cycles or Velo Orange in Annapolis, MD carry these kinds of fenders...might be worth checking out!
