First of all, I love the mod and thanks for your work on it! I find having the button cost advanced circuits is a bit expensive though, and I often want to use the item in the early game but can't afford it yet because I haven't built oil infrastructure. I wonder if you would consider lowering the cost of the recipe or maybe adding a "cheap recipe" option if you want to keep its current state. Cheers!

I agree, it is strange that it is more expensive than the other combinators. Whilst this is a annoyance in vanilla, when playing with mods this is a real problem as often red circuits cannot be rushed in the same way.

That's exactly how I feel. Certain modpacks/overhaul mods can really extend the time and infrastructure needed to get red circuits.
