Hello
so i bought an anet a8 prusa i3 a few years ago, i've played around with it a fair bit and would like to upgrade it some more but i don't know what upgrades ive have planned would be worth doing for quality of life, ease of use and over all quality.
i have already upgraded the PSU, added a mosfet to the bed and a few print to help it (drag chain for the X axis, supports for the Z axis and so on) but i dont know where the upgrades i have in mind with be worth it so if i could have any opinions or experiences please let me know.
i mainly use the printer for work on cosplay parts and odd bits around the flat and primarily in PLA but being flexible would be useful.

Planed upgrades
board upgrade to a SKR 1.4 running merlin (new screen and drivers) £40
bed leveling touch sensor £26
J-head hotend with bowden £30 (mainly of easy of changing filament)
metal frame using extruded aluminum style around £50

or do i just say screw it, save for an ender 3 and upgrade that?

i mainly just want to make the printer safe as can be and the turn on and go feeling, as is i feel like i spend more time leveling the bed than printing but id like to hear your feed back
all parts would be added gradually as i am on low income
hope to hear some good feedback
