I bought from FSLASER in Las Vegas NV.
Was a drive of 7 hours for me to go there and get it, they showed me how to align it and such, and all the workings.
Mine is a Hobby Machine, and works well for me, I make terrain for myself and a few friends, it ran about 2k, for a 40 watt.
If you want to run a service, I would suggest a 60-80 watt unit.
Epilog was out of my rage for cost, but again not a commercial use for me.
I have the mid line hobby from FS Laser, 9.5 x 14 inch
the next up in newer with a removable bed up to 60 or 80 watts, and a larger cutting area.
I do mostly 15mm so the bed is plenty large enough for my needs, but for 32mm buildings it might have some size issues.
Looked at many, went with what I could afford.
FSLaser takes a standard Chinese laser and does a few upgrades makes sure it works, and has a 1 year on hobby and 2 I think on larger units.
Also every month they give a 300dollar credit to a user picked from projects submitted. Some amazing stuff made.
I would spring for the newer unit and the 45 watt tube it has, if it had been out when I bought.
You will need software, I suggest Corel Draw, it works well, with the laser, but most anything can be used.
The main things is breaking it all down to the parts and then the materials.
One material I want is called Laser Board, but seems very hard to find, another is 2mm MDF all I can get local is 3mm or 1/8 and that is not MDF but hard back board.
I have cut many papers, even some cloth.
I have some leather I will be working with soon for patches.
I do not expect to make my money back, but it is fun.
There are many folks selling Laser Cut buildings now, so as a commercial run, I would have more than a few designed and stuff that is unlike what others have before starting.
The market seems heavy atm with them, but if you have great designs it can work, as CORSEC has proven. :)
