Behringer US600 vs Electro Harmonic Pitch Fork

Have anyone had the chance to try these two pedals? I am finally starting to build my own pedalboard, and i want a pitch shifting device only for the detuning function, i only want to go down a few semitones for playing Hendrix, SRV, or Petrucci. I've always heard that the US600 is great for this, but recently i've read about the pitch fork and seems like one of the best pedals for doing this, but the US600 is way cheaper hehehe. I would like to hear your opinions on the detune function only, i am not interested in harmonies and all the other things these pedals can do. Which one would you recommend?? Thanks in advance :D
