Zax:
You should not give people false information about our lasers when you don't own one or seen one in operation.
Our 4th generation laser are pictured here: Full Spectrum Engineering
Our XY table is completely redesigned and has two hardened steel rods with ball bearing linear slides. These are mechanically superior to the cheap Chinese lasers which have plastic roller wheels on the left side and the motor located on the right side with a single steel rod. We located the Y motor and Y mirror on the left side which save wasted space. This XY axis is designed and made for us. It is not available on any other machine. We added two enclosed cable carriers for the air assist and all cables.
The M40 is similar to our 2nd generation model. These have the XY table that is a separate unit. The cabinet area for the power supply is double the size and this cuts the working area in half.
Our model is an entirely different laser both mechanically and electrically.
You can upgrade the electronics with our electronics upgrade (at $749 this makes the price almost the same) but there's no way you can mechanically modify it to be the same. The parallel port version of NewlyDraw makes your laser a door stop. Again, we are so confident of our software superiority we offer 60 days money back guarantees.
The Chinese manufacturers will probably (poorly) copy our superior mechanical design eventually but until then you can't find the same laser anywhere else.
Again our advice is just to get a 30 day money back guarantee. Buy the cheaper one and if you are happy with it then life is good. If you are not happy with it then you can return it and buy ours.
If they have no store for you to try it and no return policy, you are surely to be disappointed.
