We have one...
Its actually great machine. If you're doing a boatload of 4x8 work all day long, then yes one with a bigger bed is going to be more efficient. However, if you're doing roll work, its great, and it even does a great job on 4x8 sheets.
We do a real mixtures of sizes and materials, and for $80k vs $150 for Esko or Zund with same function, its a real deal.
Its ability to move the materials and continue cutting (segmenting) works perfect, and rarely gets out of register. We run ours really hard, and its working great!
