I've done the MFR version, and th Steve's Carts version. When you get to a certain point with Steve's, it actually causes client crashes. The MFR one, though it takes a little more thought for planning, is probably the easiest one to do, that I've seen.
Just have to place your animal farm with sewers far enough away, or below, your tree farm so as to not have escaping animals. Then, best suggestion from there is make sure you sort the items, wood/rubber/apples/leaves go one way, saplings go another, feeding into the planter. This way, you don't have to bother with making sure it's full. I use a dual chest with redpower filters in it attached to my harvester so that the saplings and wood can be more easily sorted, and to prevent overflow and loss of items.
Filled a doublechest with logs in just under 4 hours. Also reduces much of the lag that the bc pipes create.
