Now we're talking - I assume this isn't what's in the 1.5.2 beta pack?extra utilities 0.2.3a has filters you can put on a transfer node to only pull out specific items.
Don't get me wrong; I'm not about to not use it - just not for this. It was completely to control simple overflow that you don't get with buildcraft pipes.All that being said, do what you like, I don't care that much, I just think you are missing out by not giving AE a serious try.
