Just chiming in to say I agree with the other folks here.
The Little Angel Chorus did not make me happy. I'd have kept it around for it's sound, which is unusual, but it was such a pain in the ass to make it work consistently. Even with all the "lock up" fixes, I still had to pretty much short circuit two of the IC pins with a screwdriver tip to make it act right for even a little while (and I'm not the only one). I'd say if you enjoy frustration and have somewhere to throw pedals without breaking anything important, go for it. Me... I considered backing over it with my car.
The Zombie Chorus... I love it, but it is kind of specific sounding. I'll put it this way, I'd never want it as my main chorus pedal. That said, I've spent hours playing through mine and it definitely makes me want to write something specifically for this pedal because, in it's own little corner, it really shines.
Sabro's CE-2 layout is awesome. It's a little large, but that's just how it's going to be. No getting around that. It makes a fine "main" chorus and will do a great job in almost any circumstance. Definitely one of my "keep at hand" pedals. Just take it slow and be patient building it.
