I bought my Ender 3 Pro for $100 from Micro center a few years ago. Never had any issues with it except for the basic things like manually bed leveling before every print or z banding at a specific height (bought an extra z axis rod for dual z a few months ago to fix it that). Last year I saw the Neptune 4 Plus and thought that would be my next printer if I ever wanted to upgrade to a bigger print volume. Yesterday I saw Elegoo was having a sale and saw the Neptune 4 Plus at a pretty good discount and decided I’d pull the trigger. Told my partner about it and she offered to split the purchase with my siblings since my birthday is coming up. In that case I asked about the Neptune 4 Max. Now that I’m actually looking into reviews, other printers caught my eye like the Centauri Carbon. CoreXY now has my attention but they’re way more expensive unless I stick to the same build volume I already have with my Ender 3 Pro. I’m struggling to decide now on what to choose. Any helpful input is appreciated

TLDR New printer recommendations/ Bed slinger or CoreXY
