I've tried Morleys and Crybabies in a shop. Morleys are more expensive and both I and the sales guy preferred the Crybaby tone so I bought it. Morleys are optical though, this supposedly makes them last longer but regular wahs are basically just variable resistors with a tilt switch so nothing very expensive can go wrong with them. My crybaby's lasted me well so far. A friend bought a Dan Electro which has various other settings but the tone's not as good.
If the reason you're asking us is because you don't want to one from at shop prices then why not try some in shops and then buy them one more cheaply online. Cheeky but hell, why not?
