I use a Mac with my machine…just a tip, connect whatever machine you buy via ethernet and save yourself some potential usb problems(driver conflicts)I use a crossover cable but I have been told on here that I need only use a straight ethernet cable.
I mentioned this because you listed a few requirements
Doesn’t break the bank (a highly relative threshold)
User Friendly (so)
Works with LightBurn
Meets your needs
What are your requirements such as work area size, ventilation, material thickness, speed, connection type, material depth, rotary, machine footprint, etc. And probably the most important item to go along with these requirements: what’s your budget?
The only CO2 laser remotely in that price range is the K40.
At around $1500 you will see the bigger “50w 500x300mm blue and white” that has a DSP controller, and at $2500 the even larger “60w 700x500 red and black” on eBay. These machines don’t necessarily require upgrades out of the crate, but still require a fair bit of tinkering and savvy to be able to set up and fix issues that pop up.
If you are not able or not willing to put in that work, then you should add a zero to your budget and go with a high end Chinese brand such as Thunder Laser, for example.
Also, a diode laser will not be good for cutting wood despite what it may claim.
