I have narrowed it down to :
EHX nano small stone
MXR Phase 90 74 vintage
Maxon PT-999
Red Witch Moon Phaser
4ms Phaseur Fleur (this one is very strange)
I would throw the Pigronix offering into the list
http://www.pigtronix.com/products08/ep1.html as the one I tried sounded excellent.
Personally I'd go for both the Red Witch
and Small Stone (as it was said theyre very different sounding beasties).
If you like the sound of the MXR then I's suggest buying a BYOC style kit so you can choose the style of MXR you want.
Apart from that I would also suggest looking at the Ibanez Tone Loc version as it's cheap and sounds better than anything by Boss
MDV : All I can say is that I'm stunned
