It’s definitely worth it. I use AE’s Watch Folder feature. I know other people prefer 3rd party apps like Smedge, etc., but most problems with Watch Folder are a result of not having all of the required fonts, effects and codecs installed on the farm machines, and that problem applies to 3rd party apps as well. Once you get the Watch Folder work flow down its pretty reliable. There’s really no reason to wait around while your workstation renders. Even with a small farm, it’ll render faster than your workstation, and you can be working on a different project while it does.
