difference between ross dz-1000 and "upgraded"

guys, please advise a good source for ross switches.. other than occational ebay listings.

thanks

Where are you seeing a reference to "upgraded"?  I'm on their webpage and I see RossReady, which states that they are pre soldered underneath.  Is that what you mean?

I'm sure you're looking at the same thing I am, so forgive me if I'm telling you what you already know, but it looks like Ross comes as manual, with a DZ switch machine, or TMCC compatible, also the RossReady prewired switches.

I guess the website says it best, "...choose between Manual, and RossReady w/ either the DZ1000 or DZ2500 W/ direct TMCC compatibility)

(RossReady switches come pre-wired underneath...no soldering!)

Best place to buy is straight from Ross. Not going to find them any cheaper. I bought a bunch of Ross switches with the DZ2500 which support TMCC use. But afterlooking at the options I am using DZ 1000 and Lionel ASCs to control them

i found some decent prices on cttrains.com , they seem to differentiate between the two.
