Constant, you're work is awesome. You're not just engraving crap from Laserbits.com and reselling it, you're using the laser as a tool for art. Don't worry about the scrollsaw guys giving you crap. They can't even compete, and it's not worth your effort to argue with them.
I'm sure when the printing press came out, the caligraphers barked quite a bit, but how many handwritten books are on the shelves now? My parents bought a laser engraver and it's pretty cool what you can do with it. It's a paradigm shift that will make scrollwork practically obsolete, like it or not everyone. And hey, how do you think woodcarvers working by hand liked it when the scrollsaw came out? You can hang on to old technology for a hobby and nostalgic value, but moving forward, these lasers will become the new standard and we should look to use them for all their capabilities and try to push the envelope even further. That's what you're doing Constant, and I look forward to seeing what else you can do.
