http://endurancelasers.com/giveaway-...r-attachments/

entered the comp.
Then looked at the price of your 10watt diode laser.
Holy mother !
for the same price as your 8.5 watt diode, I can get a 40watt cabinet laser engraver.
Can't find a uk price for the 10 watt.
But at $995 - about ?770, it seems somewhat expensive.

What justifies your price ?
