Since this one has both filters, I spent some time comparing them. The original filter certainly has character, but it is really noisy. I think this is the issue with all the Mini's complaints. The later filter is a little less harsh, but retains the same character without the noise: quiet as a mouse

Keyboard is great, though I did not realize that the synth is legato only. Not a huge deal, as I can alter playing technique where needed.
Overall build quality is good. Certainly NOTHING is coming off the front panel! Jacks and pots are all solid, no wigglies.
So am I happy to pay almost twice as much as a Mini? in a word, absolutely. The size is a big thing for me, especially the patch bay and keyboard. Also, having both filters is a real treat, and the possibility of mods with existing points on the pcb (pwm, single vco mod, etc.) make it truly a cool platform.
And the sound is just gnarly
