Thanks so much for replying! Yes that definitely echoes a lot of the stuff I've been reading. My thought with the Domino module was that it would do a lot on its own, and therefore be a fun module to play with while I built up the rig, but perhaps that one is not such a good choice? Would something like Atlantis, or Plaits or something be better for that? Is that kind of in the ballpark of what you are talking about with stand alone modules?

Here's where I left off, but good point about the small pots. Perhaps these little modules will be frustrating to work with:

Thanks again for taking the time to help. Yes it's a bit overwhelming, but really I can only justify buying one module a month or so, and I'm patient, so I got plenty of time to make a decent plan.
