Reason: Mod is currently very stable on 1.4.7 and the update to 1.5.2 will be along shortly. The mod itself is really big covering a wide variety of things from normal building blocks, to more advanced electrical machines, huge overhaul on rendering with 16 new stone variety's and 32 marble types and something like 48 minable ores. But really be aware, this mod is mecca huge and hasn't really been advertised or advertised at all until now and it's not that easy to craft your first batch of machines. The mods perfect for smp, all machine have been developed in such a way that you will never find the situation where someone has build a machine on the server turned it on and the never log back in leaving the machine on and server resources wasted when ever that chunk is loaded.
Great detail has gone into the pulling the mad together maintaining a balance in the game itself and providing you with a unique new flavor.
Downside to this mod is because it's so huge a lot of information lacks in regards to what the mod can provide you as a whole, the dev team have been busy updating their wiki, but theirs still a huge gap that needs to be close so, making it in some instances a really hard mod to play or use, think the mod adds something like 3000 recipes, all crafted on super cool new work benches, 30 new machines all models with unbelievable detail and as the developer said in this block what you see now is merely a tip of what more to expect.
So really worth looking into
