Cool :).
I've been kind of staying away from TOO much EQEx stuff for now, because I want to experience IC2 a little bit vanilla first, and then upgrade things with EqEx stuff. I waited a while to make that destruction catalyst for that purpose. Wanted to see how the mining drill and laser did on their own. Thats also the reason I'm not doing the macerate gold -> Diamond cycle a lot, it feels a little like cheating to me :).
I'm also using all my diamonds for IC stuff, so haven't had a chance to make too many items from EqEx. I'll probably get an Obdisian factory going at some point, but that requires an awful lot of investment up front. Obsidian factorys are useless unless you have the Volcanite, Evertide, and Gem of Eternal Density -- so thats like 9 dark matter right there before I can start using the cheaper recipes to duplicate them.
I think Epsiode 2 of my EqEx series featured my Obsidian factory from my old world, I had like 48 of those things all pumping into a chest, it was insane.
IC2 is really the star of my LP series, for now at least. I'll go into more EE and BC stuff soon though :).
