I posted several years ago regarding a 3D printer and members steered me to considering laser cutters. I had health and financial issues that kept me from really finding one. Recently I have been looking at the ones on eBay and also others such as the Boss. The eBay cutters are a lot more affordable but all have things that make me to hold back. I found a lot of hidden charges such as lift gate service residential delivery fee etc. Also there is not one that I can confirm that is ready to cut or engrave without purchasing other things such as software vents and coolers.
What cutters do you think I should look at? I want to use it to build structures for my railroad and possibly make some to sell to help offset the cost. My wife is the real craftsy one. She would like to make signs and other crafts which would include wood, plastic, cloth and paper. I really don't think I can afford those similar to the Boss because by the time you add on the extras its well over $5000. Is there a more affordable cutter that I can consider? Should I risk buying one of those less expensive ones on eBay? If I go the eBay route what other things do I need to purchase such as vents and software? If I need software what software do I need?
Also for those of you already using a cutter can you provide some information on how the design gets from my PC to the cutter? A lot of these state USB port but I'm not sure if that's a cable from my PC or a USB thumb drive.
Any help that you can provide is appreciated. This is a major expense and I need to make the right decision.
