E-H "The Clone Theory" reissue is kinda like the chorus half of the Poly--it's analog. I heard one and liked it. THeir new "Stereo Electric Mistress" has mixed reviews, I'm not sure if it is analog like the clone, but it too is like the poly.
I've used the poly, and it is pretty unique. What sounds are you going for? Chorus or Flange? Personally I really like MXR flange and chorus sounds.
