So I've reluctantly switched over from buying a Chinese laser to an Epilog. Right now I'm eyeing either a Mini-24 60w or a Helix 40w. I'd prefer the larger Helix but I'm concerned that 40 watts won't be sufficient for cleanly cutting thicker wood, acrylics and leather.
Anywho, the sales representative is pushing me toward the Helix even though it's a little cheaper. To combat my concerns he recommended a $300 upgrade to a 4" lens which leaves a wider kerf, but cuts thicker substrates.
Has anyone had an experience with that or do you think it would do the trick?
