Out of those I would get the Dime Wah from Hell. Has selector switch for frequency, a db boost, and has that traditional shape.
Another good one you don't have listed is the Ibanez Weeping Demon, does basically what the dime from hell does (having the adjustable rotary switches), but this one automatically turns off when you take your foot off the wah. And cheaper, cause it doesn't have dimes name on it.
