You might want to do a little research on an "Ornaments & Crime" module and the Expert Sleepers Disting Mk4.
They aren't dedicated modulation modules. But they have LFOs that can themselves be modulated as well as other sources of modulation (sequencing, quantizers, etc.). Each one will be under 300EU, definitely. The O&C gives you more modulation while the Disting has some audio effects (resonators, reverbs, delays, etc.).
What's nice about this type of module is that if you find yourself using a particular aspect of it over and over, you can then make an informed decision if you might want a dedicated module to perform those functions freeing up your original module to perform other functions.
Get the Moog out of your case. HP is expensive and you'll probably add more modules as time goes on. No sense in buying another case or a larger one when your Mother can sit right next to it.

I already had looked at the expert sleepers module, but the lack of clear controls are a bit offputting, but that was just the first impression. Ill look at it some more. O&C looks interesting as well and seems pretty cheap for what it does. Ill definitely keep that in mind. Thanks
