Wow, Prusa just announced the MK4S with major upgrades to the MK4 printer. I love my MK4 and when I heard about the new features I was wondering if I could justify the investment. Then they announced the upgrade is only $99! The new 360º cooling and higher flow nozzle are two things that stick out to me.
