Currently asking myself the same question. Due to space constraints with my current setup I'm trying to decide if I want to replace my current oscillators with a complex oscillator module, or use my existing oscillators alongside something like an SSF Zephyr or ZPO. Currently leaning towards the latter, or just picking up a Befaco Pony for now since I could easily keep that in the rack if I change my ind later. Finding a good deal on a Cs-L might tip my hand, though.
