Got the opportunity to grab a 2011 vintage FSL 40w CO2 hobby series engraver for $600. It has low hours but has sat in storage for almost all of it's life. Is it worth it to get this thing? I know the company seems to be a bit lack luster in the customer service dept. I have no problems modifying stuff if need be, both mechanical and control wise. Just wondering if it is worth it to jump in on this? It has the potential to pay for itself really quickly. It would be kind of a stop gap until business picks up to the point of being able to get a proper machine in here. Thoughts?
