I have a FLA-100 machine I bought a kit and all the electronics and Mach3 I got it all for a good price. I have had no problems with the machine it went together very easy and is solid. Now they lack in customer service it is hard to get Nate to respond other than that he puts out a good product. The CRP4848 made by CNC Router parts is a excellent choice a very good machine you will not go wrong there and there customer service is great second to none Ahren is a good guy if you have a question he is right there to answer you. Hope this helps...
