Has anyone used the DP50 or DP504 or DP120 from Perry's Milkers? I'm really thinking about getting a milking machine from Perry's and wanted to know other people's opinions. So far everything I have found on the internet has been positive. I'm leaning towards the DP120 but still want to make sure I'm making the right choice. I mainly have Nigerian Dwarf goats but I do have one Alpine Mix doe and a Boer doe. I am currently milking 2 Nigerian Dwarfs and my Alpine. It is just taking too long to hand milk and I'm worried about getting arthritis or Carpal Tunnel from that constant repetitive movement of my hands/fingers.
