Hey BB
If possible outsource your FB cutting in the short term. We printed with Onyx, generated Zund marks and dropped off the media and cut file on a thumb drive to a local printer for finishing.
Of course we had issues with timing as they fitted in our jobs when the Zund was free but we managed that as we had so much time freed up. I looks at EVERY cheaper option for our own FB/trimming option over 2 years and eventually purchased a 1612....we’ve never looked back (should have done it years ago). You say you can’t afford it right now....truth is a week in from owning one you’ll be looking at new markets and will have no idea how you managed without it....it will literally change your life. Good luck, stop overthinking it (I’m the world champ of procrastination) and sign the order.
