Like many pedals, phase pedals are very subjective in tone. If you're evaluating them without listening and playing through them, you're doomed. Go to TrueTone in Santa Monica or a local Sam Ash/Guitar Center and try several out. For under $100, I liked the MXR Phase 90 best, but it's also an effect I use sparingly to never.
I like the MXR Phase 100. Switchable waveforms, but still simple to use. It sounds like I want a phaser to sound, my reference / first encounter being what Peavey used to feature on their amps long ago.
I got the EVH version of the MXR phaser. I love it in it's script mode. I probably overspent on it since I only needed something simple, but I do love it. I also got the flanger on the same day, I'm such an Eddie fanboy.
