I have had a CueMonster for many years now and it is about as trouble free as you could expect.
it just keeps amazing me as to what it can do.
About the only limits are what you are able to think up and program.
The machine is capable of doing things that I have yet to understand ... and that is a good thing.
The machine is like all automated equipment in that it does take some learning and mechanical skills to program, set up, and operate.
You need to have the ability to troubleshoot what is wrong when you are not getting the expected result.
Not everyone can do this just as not everyone has the skills required to operate other cuemaking equipment.
If you have mastered the pantograph and are making your own custom patterns but finding you are restricted in what you can do with it, you are most likely ready to move up to a four axis CNC machine like the CueMonster.
It is not the most expensive machine available and I am sure it has some limitations to cue inlays but it will take you many many years to reach that point.
The second and most importaint part is that of support after the sale.
Who do you turn to when you are stumped?
Brian and Jim have been around for a while and are a great source of information and problem solving for the cuemaker.
Plus there is a large experienced base of CueMonster users that like myself that are willing to help you solve your problem.
