Kerr vs Rio's Electromelts

I see where Rio has a tilt and pour electromelt which I believe
would be easier to use than the one which requires lifting of the
crucible out of the cradle with tongs. I would appreciate information
from anyone who has used the new tilt and pour electromelt.

Mainly, I am concerned about its weight, which is 13.6 lbs. This
seems to be rather heavy to lift, and to get it into position for a
smooth rapid pour into the small sprue opening in the flask.

I am wondering if it would it be better to get the more expensive
Kerr electromelt which weighs half as much as the Rio, and does not
require a weight lifter to handle.
