I currently have the Dunlop Slash Wah, the CFH and the Zakk Wyle Wah. I like the simplicity of the Zakk a lot and it is just within yout budget (at GAK).
I think it's better than the standard Crybaby, it has a bigger sweep and a Fasel. It doesn't say it's true bypass anywhere, oddly enough I found that it gives a bypass signal even without battery or power, I guess it might be then. Admittedly I've only fed it quite strong output humbuckers, so I've not noticed any tone loss. Strats might behave differently.
I also had a Morley George Lynch Wah. The switchless sweep works awesome. If now only Morley could come up with a Wah that doesn't sound sterile, screechy and/or totally lifeless I would dig their stuff.
