I'd also be interested in seeing what the OP went for too. We're thinking of upgrading our MPM3000 series. Has served us well over the years but is a bit dated to say the least. Not heard much about the SJ Inno. machines here in the UK. Would prob

Sup G! Normally when spray fluxers get neglected, the spray pattern is the first thing affected. To actually 'see' this, we cut out a piece of cardboard the same size and length of the board. Run it over the fluxer and then turn itover and look at
