Denon TT'ers

As I posted previously, my son has fallen in love with the styling of some of the Denon TT's. I just acquired a DP-80 for which I will build a plinth in order to give this table to him for Xmas. Special thanks to audiogon member rwwear who put me in touch with another meber from whom I bought the tabla.

I have rebuilt a number of tables, but never a Denon. Does anyone have tips with respect to tricks and tweaks for these tables? Best arms a consideration, too.
