I really appreciate the replies! I've kinda decided that, probably the smartest (not the cheapest) move in the longer run is to get an Intellijel 7U (104 HP) and get at least 2 quadratts and then some. If anybody is selling theirs and is willing to ship to Finland hit me up :)

I don't have any 1u (I think it's incredibly expensive* for what it is in terms of case cost - & I build most of my cases!) but if I did I'd want the intellijel noise tools module

*adding a 1u row to a case costs the same as a 3u row, can only hold 1/3rd the functionality and only saves 3.5" vertically

I'd buy 2 tiptop mantises over a intellijel 7u anyday!!! cheaper and way more usable hp plus arguably much better power!

Good one on the matrix mixer but the only one I've ever considered was the doepfer one, which is unfortunately huge. I've seen some smaller ones, but they usually lack the possibility for cv control, oh well, maybe one day!

the doepfer is incredibly well sized due to ergonomics - I have 2 smaller ones (pusherman and york modular) and they are too small and cramped

you might want to look out for a used rebel technology mix 04 - they are as far as I know discontinued - only 10hp, cv control over everything, but then you need more modules to control it!

Utility modules are the dull polish that makes the shiny modules actually shine!!!
