Your reply makes me think that alternative to what we have discussed so far is not a viable option, so I'm going to stay away from it.

Currently I'm on MakerFarm's website and I'm looking at the Pegasus. I see Extruder options. I'd like to go for a dual extruder, as it gives more options, but I'm not aware of the difference between "e3d-Lite6 hotend" and "e3d-v6 hotend."

Another question I have is how "susceptible" (for lack of better word from the top of my head) is the Pegasus to hacking and me printing parts for the printer itself?
1) I don't know what hacking in terms of 3D printers means but I have seen it during my research.
2) You were perfectly clear that plastic parts are not as reliable as metal parts.
