Hopefully not too late of a reply... We currently have both, the Ersa ETS 330 (running LEAD solder) and Seho GoWave 1030 (RoHS solder). Bought the Ersa used, and it seems like a strong built industrial high volume machine. We've needed to modify it a bit to fit our needs, but running fairly well with few hicups. The downfall is maintenance and cleaning. Difficult to clean dross out of the solder pot, and fluxer cleaning. The Seho GoWave is a nice little machine designed for moderate usage. We bought this new 10yrs ago and no problems as of yet. It's very easy to clean, operate, and maintain. If our Ersa machine goes, we would most likely be looking into purchasing another Seho GoWave.
