Oh yeah. But since I already had the Core One the INDX is the obvious upgrade path for me. I also only got the 4 head version.
I started with a MakerBot Thing-O-Matic when it was new. After leaving the hobby for a while I got a MK3(S?) because it seemed the most reliable to me at the time.
I’ve stuck with Prusa since then since I’ve been happy and I’m used to their stuff. I had a MK4S because I could upgrade my existing printer to it. The next time I was interested I didn’t see anything I was more interested in so I stuck with what I liked. There is also a “known quantity” factor in the company since I’ve dealt with them a few times now.
I would leave them if I saw something I liked better, but haven’t at a time I was buying. I do like the look of Bambu printers much more. I looked at their printers for a minute when I wanted to replace my MK4S but didn’t like it enough to bother. I didn’t get a Core One until after the INDX was announced, and that was a big part of why I decided to upgrade.
If I was starting over the U1 would be a VERY big draw for me. Price/capability is very impressive. Prusa’s low end is quite lacking as far as I know.
