I'm a newbie here too. Found this forum to find 3D printer parts but haven't found an answer to my question yet.
When I was looking for a printer for myself, I was asked almost the same questions. When choosing, there were 2 important parameters - the possible transportation and printing of large products. I found Dremel Digilab 3D20 for myself, and when I bought it, it cost a little over $ 500. I am sure that if you look for it, you can find it for 500. Well, or buy from someone else (I mean previously used).
