Check out Takaab/Siam Modular, I have very good experiences with their utilites and they're really cheap.

It shouldn't be like this. Synth can be affordable

If affordable is the main point, why punish yourself with Eurorack and not get a Korg Minilogue XD or an Arturia Minifreak? Put some drum loops on your DAW and you'll be churning out bangers in no time.
