So the Bambu labs A1 looks like the perfect starting point.

One problem, it uses proprietary firmware and software, I'm a big advocate for owning the things you buy, and not supporting companies that don't allow you to do that as much as I reasonably can. So yea I can't buy Bambu.

The Creality SparkX i7 seems nice, it looks like a straight up clone of the A1

I've heard a lot of people complain about Creality though, so unsure. I'm a bit stuck and getting decision fatigue.

My budget is ~500 Euro.

Help.
