Went by Wally World after work yesterday, they didn't have the battery operated one. They did have the mechanical one that most gas grills use, the spark generator is built into the button housing. Came with two different electrodes for under $11. The long electrode required careful bending to orient, but will mount into pre-existing holes on my Blichmann burner. Will grab a piece of aluminum to mount the button and I'm good to go.
