While i know i am not Moasseman i'd like to state that he has a point. Not necessarily with TE (TE is fairly balanced and works like a charm).
MFR and Forestry on the other hand have a somewhat terrible balance when used alongside.
Forestry Farms are a bit expensive but get the job done for you.
MFR Planters and Harvesters are cheap compared to the farms and so are the upgrades. AND you can have a fully automated farm with fertilizer which can be produced and not needs to be mined.
There are some other examples of cross-mod balance which are off (Soul Shards anyone?). The huge main Mods try to balance against each other (also caused by having a developer working on two or more main mods) but many small ones are not equally balanced against a larger pack.
ROFL.. try using the config file Lathanel. You can make MFR and Forestry very very balanced.
