Well the small stone has no real range to the sound, there isn't a lot you can do with it so if you like it great if you don't hmmmm not so great, bypass can be sucky on the russian ones and I've always noticed hum on the EHX modulation pedals I've tried but this may or may not be a concern for you, if you can pick one up cheap second hand go for it. I've always been a bit of a sucker for the 80's Dod pedals so maybe see if you can find a phaser on ebay.
