sorry to add to an older thread havent been on in a while. Yes there are draw backs to using a laser. Cost is a big one. The laser I use is a 350 watt galvo style laser and it cost about 225,000, but its like brand new on the market and we are one of a few to have one. You can see it in action here
Our costs to use the machine are more than reasonable. Our labor rate is $120 an hr and I don't think that you will find any better than that anywhere. I use it to cut, and lightly mark out my tool lines then hand finish it. When I made the video of the machine I did a lot of leather marking and put it in there as well as other items. The edge does "soot up" but nothing plain ole water wont take care of. The Italian company that made the machine use it mostly for leather parts for shoes and such and they actually take the parts and have them dry cleaned. If anyone is interested in what would be needed on your end to get some work done by where I work at or most any reputable place for that matter I have a video detailing the basics of what you would have to do to get some work done.
If anyone has any questions message me and I will try to help you out.
