If you're cutting anything thicker than a 16th, then yes. Clean square edged cuts. I inherited a 1600mm big bench with an original Javelin Cutter, when I joined our company. Great for PVC and foam board, and at a push, have used it to cut Dibond (bought a Steeltrack for better productivity).
Printer, laminator, bench, cutting system.
Bench mounted means you can apply more force for tougher substrates (and not pick up a "floating" bar, by the wrong bit of the blade holder), and most of the bars allow you to dismount them, so you can make longer two part cuts.
In the UK, spares are readily available, as is very good customer support. I'd be surprised if spares aren't available left pond, so as long as the bar hasn't been abused, a second user model can be easily refurbished.
