Good deal?
Depends on what N2 system it comes with. The marker costs about $125 and the loader about $40.
If you go with the Custom, put aside about $50 for a better barrel. In fact, if I had to choose between a motorized hopper and a new barrel, I would go with the barrel. The Custom's stock barrel is even worse than other stock barrels.
N2 is a good idea with a Custom since the marker doesn't have a regulator or expansion chamber to help stabalize co2.
