***UPDATE*** - just found out that the above unit, although it looks like a professional model is continuous technology, not pulse. I have been told with continuous laser, you run the risk of compromising the material, not just removing rust.
Anyone have any experience with this one? I have emailed them asking if it is continuous or pulse technology. Still waiting to hear. 1500W is about $4,500 USD with shipping.
Do you think if you had one of these you could advertise and make some $$ to offset the cost? What would people pay?
