I have looked at AE2 several times and I actually want to learn the mod. I have a thing about playing 100% legit though, no cheating, so getting the parts tends to take a little time. I was actually looking for a stop gap measure, something that I could put in place that has insane storage capabilities but isn't as expensive as AE2.
Iron chests is the one that you can upgrade from iron > gold > diamond > crystal/obsidian right? Yes I use those currently, but even the top level chests are small imo. The Draconic Chest is actually the largest chest I have found, but again with playing legit, getting the draconic ore can take a while. Mid/late game what I envision is running ender quarries in a 64x64 size, with 4 of them lined up in a 4x4 pattern. I want something large enough that I can dump their contents into before sorting them with whatever method.
AE2, from what I have observed, seems to just throw everything in a grid without any kind of sorting... granted I don't know the mod, but that sort of disorganization drives me nuts.
ShadowHawk707: I just discovered the storage drawers mod last night and was considering adding it in. It is nice to hear another person recommends it.
