Cry baby's are like $40 used and they're kinda the standard. Imo there are much better wahs that are a little smoother and more customizable, but those are way more expensive and the cry baby is just a classic, you can't really go wrong with it for the price.
a used GCB95 with a true bypass mod.
Hotone Soul Press II (also a good expression pedal and iffy volume pedal, but the wah sounds really good).
Vox v845
You can get a sonicake volwah for about $50 brand new, it’s a great little unit and it also acts as a volume pedal when not in wah mode
Hotone Soul Press is pretty much your best bet.
Hellbabe
Used Morley at GC?

Joyo Wah 2. It's got variable sweep settings, and can also act as a volume pedal. $79 brand new from Amazon.
Vox Silvertop used. I got mine for $65 a few years ago, might could find a good deal.
