If the budget in question is around EUR 800, it seems to me that you might get loads more out of one of two possibilities...
1) A patchable. These can be pretty potent devices...and the pairing of the Make Noise 0-Coast and 0-Ctrl are being referred to by some as the "0-Easel", after the Buchla Sound Easel. There's some others that kill, too...Platypus's ANTS!, if you can find one, or Kilpatrick's gateway-drug-for-Serge, the Phenol.
2) Not Eurorack. Instead: https://www.tangiblewaves.com/ The nice thing about the AE system is that it mainly consists of "primitives", or the devices behind the "nicer" modules that make them do what they do. Ergo, it's easier to build with, it's WAAAAAAAAY cheaper, and in the end you don't really give up much by going with AE than Eurorack. For example, the Maths...you could do much of what it does with two AE SLOPE/EDGE modules and some logic and CV mixing. Plus, the AE Starter2 goes for a mindwrenchingly-cheap EUR 435...WITH VAT...and has ample room for more modules. AE also has Dove Audio working with them on a killer wavetable VCO, and others developing other 3rd-party modules...because the system, like Eurorack, is a 100% open standard. And they're DIY-friendly...they even have a prototyping module, the BR[AE]DBOARD.
