Hi, Daniel. You may need to hunt for quite a while but they do show up on e-bay now and then. I found my PM1225 last May and was lucky enough to find it with a matching tender, new at my favorite LHS. I did get a discount from retail but I don't remember how much. When I went for the scale P.E. tender a few months ago I ended up getting it for under $390 when I expected about $430. So, they are still out there.
To answer your question though, I'm thinking it is going to run you in the neighborhood of $1400, but you could do better.
Do you already have Legacy?
