Trust me, after the split from structural upgrades and function upgrades, if that's all you're using it for, you ought to check it out again.Only two things tempted me to get JABBA, the unifing aspect wherein oredict enabled stuff will join into a barrel and become that type. And you can I/O from all sides. Though stuff I generally end up keeping in barrels once I go to AE will become a DSU or potentially a Mek bin (have not played with those yet). I just cant see adding redundancy to my modpack in that fashion.
