Something less expensive than the Voicelive and better than Digitech Vx400?

experience with Vocal Harmonizer products?

Are any of you using the TC-Helicon VoiceWorks, a DigiTech Vocalist, or any other vocal harmonizer? If so, could you please share what you are doing with it, and what you find works well and not well?

I am just starting to research ways to simulate a horn section with one of these devices. I am mainly an alto sax player, and I am the only horn player in our covers band. I have been using a keyboard, a MIDI footpedal controller, and a sound module (Roland XV-5050) to try to create additional horn sounds. While this approach has worked well for certain cases, I have come to realize that I am not able to duplicate the exact same rhythmic feel for moving eighth notes on the keyboard, as for what I play on the sax - after listening to a recording I found that the "horn" notes I was playing on the keyboard sounded "square". So my thought was that a vocal harmonizer might work better for such moving parts. I'd appreciate any advice or experience that any of you can share - thanks!
