Electro etch the bad boy yourself
I'm serious, a battery, cue tip, and salt water and your golden. Practice on an old knife first and wrap what you want to etch with duct tape. Since its just the umbrella logo, it should be a real easy stencil to cut out of the duct tape. Connect the positive end of the battery to the knife and the negative end to the cue tip with alligator clips. Dip the cue tip in the salt water solution and "paint" over the stencil. Don't leave it in one place, keep it moving in a circular motion or else you risk etching too deep in some spots. That's all there is to it! Just be sure to practice practice! It's a skill you can learn in an afternoon.
