I recently brought a ECM97 system. Got it going pretty good now but did a few custom mods to make little custom tray tables etc as feeders and such can be soo expensive.
I have a vibatory feeder for the ECM but it really is just a vibrating plate on mounts which we removed as it was taking up too many slots on the machine so we mounted the vibatory feeder at the back of the machine.
The big problem I have with the vibatory feeder is that it works alright when the tubes are full but once the tubes start emptying, the vibratory feeder doesn't work very well.
I would like to make a better top for it but have not gotten around to it yet.
