It’s worth it if you have the time and willpower to invest in the machine. They can print ten jobs adequately and then your bed adhesion can go to hell out of nowhere on the eleventh and you have to spend some time troubleshooting it. There are fewer such headaches at higher price points, but no machine is going to print perfectly every time. I’d recommend making sure you’re able to monitor your print jobs either in person or remotely with a webcam so you make sure you’re not wasting loads of filament and having to clean up or replace parts in the event a print fails.
