Lot's of good wahs around, depends on your personal preference, basic Dunlops used as cheap as $25, yes, $25! For a bit more the Dunlop with a red Fasel sounds a bit better IMO. For a really good wah you will spend more, I like the Fulltone Clyde wahs, I have seen them used under $100 but usually a bit more. Teese makes good wahs, used $100+ The Chrome top Vox wahs sound pretty good and are around cheap used. eBay, Reverb, The Gear Page, GC used , lot's of places to find a good used wah.
