Dialog-is there an upgraded Version?

[Whitcomb]

I just purchased a second (white) Phantom for what I expect to be much, much better than one, and of course need a dialog. Searching for one online seems to a bit confusing as some say there is a "newer" version. Is this true? seems I can find one for $329.00 vs. the "new" version for another $50.

Secondly, I'm looking for the trestands so if anyone can steer me in the right direction, I'd like to purchase them from someone reputable.

Thanks!
