I bought a 50*70cm "60"-watt unit online for about €2000 shipped. It is the size of a chest freezer. It works reliably, except that if you don't power it up with the laser armed, and instead flip the safety switch after power up, it will not fire the laser. I had one Hall effect endstop fail, but everything apart from the enclosure itself is COTS commodity stuff, so I just got a pack of new endstops on eBay and fixed it. Cooling with an Ikea tub full of water, vent with a hose out the window.
