I work for a wholesale company in the gift industry. Our company has a Trotec Speedy 300 for an "all-around" laser. We do not currently have the rotary device for it. I don't have any complaints with this machine so far. We're looking at possibly purchasing another laser to handle all of our cylindrical products. The main products we're wanting to do right now are glass vases and drinkware. This laser would be dedicated to cylinderical products (always using the rotary device). I'm not trying to start a Chevy vs. Ford debate. I'm fairly familiar with the differences in the lasers themselves, but I didn't know if there were any major differences with the rotary devices. I'm hoping the members that have experience with the "big three" rotary devices can chime in with some pros and cons of each brand, or even their favorites. Thank you in advance
