I got the Ender 3 Pro - better build surface, replaced with glass though, better PSU etc - only change I added a Petfang setup to it and a few other bits like installing Klipper3d firmware onto a RaspberryPi, BLTouch probe etc etc all in all happy with it - wouldnt go for the standard Ender3 had a look at it initially and decided against itI did some research yesterday when this came up and put first the Ender 5 and then the CR 10 into a wishlist for future research. If I can stay around $500 including necessary mods I'll be good to go. Still haven't done enough reading to understand the material differences or software learning curve, etc. I'm motivated though and plan to watch some more tutorials and study more soon.
