Ok, I'm going to jump in with my 2 cents. Having been doing as a business for the last 6 years I have some opinions to share.
1. This is definitely a area that you get what you pay for. Even though they claim to be made in the US, many of the parts shown on them look identical to the stuff coming out of China. The ones completely made in the US are head and shoulders above anything out of China. It is like comparing a industrial sawstop to a contractor saw from Harbor Freight. They both will do the job when new but the accuracy and longevity are questionable. My Universal laser is over 10 years old and When I call Scottsdale the service and support is the same as it was the day it was new. These people bend over backwards to help you any way they can and never charge a dime for support. Any firmware or driver upgrades also are supplied at no cost. The company has been around since 1988 and are very well known in the industry. They don't spend near as much on advertising as Epilog but both machines are the standard for what they do.
2. From what my research and other contacts in the business have told me, the Chinese machines have many issues. First of all they are water cooled where as both Epilog and Universal are air cooled. That means you need to have a water chiller and it is one more piece of equipment to fail. My laser still has the orginal tube in it and it is still going strong after all this time. I have heard of Chinese tubes lasting as little as 20 hours. One problem with most of the lower cost lasers is that you never know if or for how long parts will be available. Without parts it becomes a boat anchor and those of us with Delta machines know what that can be like. The cloud part of this machine is a big red flag to me for the reason that others have expressed. They have to much control over your purchase.
3. There are additional things you need such as an exhaust system, a compressor for air assist and software so the laser is like a lathe in that it is only the begining in spending department.
4. It took me almost 2 years working full time to become what I felt was proficient in using my laser to it's full advantage as well many dollars of scrap learning the hard way.
If I wasn't using the laser almost full time as a business, there is no way I could could justify having one.
Just my 2 cents.
