My DG is sitting in my living room for those overflow days. I have the Aria in my store. The DG did about 800 frames before it was moved to the living room. Good machine...especially for the money. I changed the clamps to the Aria clamps which are a substantial improvement over the standard DG clamps.
The DG is a true constant pull machine. It's a rotary head with a split drum string clamp. It works well, but it's not as good as the Aria which has a rotary head but it has a linear gripper integrated into the head. For the money, the DG is very good. Again, if you decide on the DG, get the Aria clamps.
