I have to admit that I don't currently own a guitar with a whammy bar. The occasional benefit I received from using one never seemed to outweigh the tuning issues and sustain compromise. I like the look of the Wilkinson, because it seems fairly unobtrusive visually. I like the sound of Bigsby's, because they seem to get a lot of mileage out their subtle waver. I've considered whether or not I will want one on a future guitar, but I'm not currently inclined to have one. People like Jimmy Herring make it seem unnecessary anyway, and aside from some Pink Floyd songs my band plays, I don't much feel the lack of one.
