I've got a Polaron and I dig it! It's pretty juicy. Having said all that, and in spite of all the searching and researching I've put into looking at phasers, I've actually taken the Polaron off of my main board in favor of my trusty Boss PH-3. I know, that completely flies in the face of all that's holy about phasers, but the truth of the matter is the Boss just makes the phaser sound that I want to hear. It has adjustable stages, like the Polaron. The PH-3 is a bit easier to dial in than the Polaron, 4 knobs vs. 6 knobs. I've got the PH-3 at 10-stages with the Rate at 10, Depth at 1, and Res at 1(all values are clock face), and it sounds amazing. There's no mix knob, but there's no low-end loss either.
I'd say if someone is looking for a phaser on a budget, you should at least give the Boss PH-3 a shot. You might be pleasantly surprised at how good it is. I'd still like to have a Spaceman Explorer Deluxe, but I'm honestly content with the Boss PH-3.
