I ordered just the other day. Only reason I am posting is to say that after having my MK3 for about three months now, I elected to upgrade the MK2s to the 2.5 rather than the $500 MK3 upgrade.
Don't get me wrong, I love my MK3, but with all the lingering issues and the fact that my MK2S still prints better than the MK3... I finally decided to go with a 2.5 upgrade rather than the 3. The ONLY thing I will miss is the sturdier frame. The 2.5 will have everything else that I want.
