Nice - I have a York Modular Active Matrix Mixer and a Reverse Landfill Video Matrix Mixer - If I ever get another - and you never know, the AISynthesis one is at the top of my list! Don't forget to experiment with feedback mixing!
Next purchase looks like a power upgrade, then - I've got an befaco excalibus kit in the mail (overhaul of power for case 3) - I've got one already (case 4) and it seems solid and reasonably priced + it doesn't take up rack space!

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