+1 0 -1 thx for the fast replies! i have decided to go with the MK3 for now. i will probably end up printing parts with it in combination with my lasercutter and some mechanical parts from my old printer to make a brand new big volume 3D printer. i'm thinking of a slightly modified hypercube, in order for it to use laser cut acrylic instead of aluminium extrusions. i ordered the kit version of the MK3, i hope i will be able to build it without too many issues.
