I am looking for thoughts on this topic. I own 3 Prusa Mk3S printers of various flavors. I had 5 and sold 2 of them for more than I paid for them. I am contimplating upgrades. I bought one MK4 and love it.
MK3S
MK3S with Mosquito and Bondtech extruder
MK3S with V6 and Bontech extruder
I am really town on upgrades.
MK3S to MK4: $579 - Includes almost everything - keep old bed and frame
MK3S to MK3.9: $499 - Nextruder and new first layer system but you keep the XYZ motors, bed, and frame
MK3S to MK3.5: $248 - keep nearly everything but get new 32bit control board and screen
All will do input shaping, but only 3.9 and 4 get the new leveling system that is fire and forget.
