Small single-pedal sized multi effects

I’ve been searching for a single-pedal sized multi effects pedal to fill the last spot on my pedal board. Personally I want something that could do octave up/octave down (like an EHX Pog, but in a smaller/cheaper pedal) and the be a delay or chorus if I need it. After Googling, I didn’t find much of a definitive comparison list, so here’s a list of what I found. Let me know if you know of any others.

Update 1: I realised the iStomp Shape Shifter plugin doesn’t do chord/polyphonic tracking very well, so that’s now out. There is the Z-Cat Poly-Octaver 2, which also has Reverb and Chorus, so that’s almost multi fx – 3 pedals in one. There’s also the Mooer Pure Octave (and other mooer pedals) which are so small, you can get more than one for the same space on the board for different effects.

Update 2:
Polyphonic Dual Octave Harmonizer List:
– EHX Nano Pog
– EHX Pitch Fork (More features than the POG)
– Z-Cat Poly-Octaver 2 (has a 20ms delay)
– Earthquake Devices Organizer (turn the octaves down to have less woble)
– Earthquake Devices Pitch Bay (has a little distortion even with gain turned down)
– BOSS PS-6 Harmonizer (tracking issues with Chords)
– Mooer Pure Octave (doesn’t sound like it tracks well)
– TC Electronic Sub-n-up (and sub n up mini)

Update 3:
Neunaber technology just announced their Stereo v2 pedals, which while only doing a single effect at a time, can have up to 4 effects switchable with 2 presets each. I recently bought a Slate v2, and if you’re looking for something more high end than everything else on this list check them out at neunaber.net.

Update 4:
A few other multi effects pedals:
– Nux Mod Core (Modulation only)
– Hotone Xstomp (and Xstomp mini)

	Digitech iStomp The iStomp itself is one of the cheapest around, and Digitech recently made most of the iStomp pedals free. I’ve owned one of these before, and it does have an octave up/down effect. Main disadvantage is that it requires an iPhone to change effect, and its also a little wider than a standard pedal.
	Zoom Multistopm MS-100BT / MS-50G Unlike the iStomp, this pedal has more editing features onboard and can do more than one effect at a time. Like the iStomp the MS-100BT can be updated with new effects via an iPhone (MS-50G is standalone), but there is no octave up/down sound yet. Update: I’ve just seen that this has a pitch shifter, so you could at least get octave up or down, but because you can run more than one effect, you might be able to add it twice and get both up and down. It also has a Z-Organ patch which seems to a polyphonic up/down effect Update 2: I bought one of these, none of the pitch effects including the Z-Organ track well at all, and while its a fun pedal to own, its not good enough for nice ambient swells.
	Korg Pandora Stomp This pedal does tons for the price, but seems a little complicated for live use. It does have pitch shifting effects, but I’m not sure if it can do the octave up/down thing.
	Behringer Digital Multi-Fx FX600 Behringer make great value stuff, and this pedal seems to have a really straight forward interface. I’ve heard bad things about the sound quality on this one though.
	Beta-Alvin Multi Effects ME-100 One of the new low cost pedals to come out of China, but I’d never heard of this brand before. Seems to have a nice simple interface, but a limited array of effects.
