So, I received the Rohm chuck today, cleaned the taper and arbor and stuck it the DP. The amor and chuck were just pressed together using the DP. I'll pull it and reseat it better later on. My initial measurements show the runout to be .002. The Golden Goose keyed chuck was .004, and the Jet keyed chuck was .007.

I'm going to use the Rohm chuck in the GI at home, the Golden Goose chuck in the Jet at the shop, and clean up and keep the Jet chuck as a backup or for when I sell either DP. Thanks for all the advice everyone.

Oh, and as smooth as Rohm is, I can only imagine how nice the Albrecht is for an extra $130.
