I just bought it. I ended up buying form MacroMonster. From reading reviews on various Corel, CNC, and other forums, it seemed like there might be a better buying experience and possibly better relationship between MacroMonster and the developer.
It’s pretty cool. So far, I have played with the customizable puzzle piece creator and the finger joint box maker (complete with kerf compensation capabilities).
There’s a ton of stuff in here that anyone using CorelDRAW for laser, vinyl, or CNC should take a closer look at: nesting, find duplicates, DXF export, trim and contour tools, and a bunch more.
Here are some links to more details of the features:
