The SRP was $269.99 when release - I recently say on Ebay a set for $999.99 - no bites, they are nice but not that nice. As I have searched the cheapest I have seen them is $575.00, over double SRP, again, nice but not that nice. I will save my money, buy an engine or something else.
In the meantime - the search continues.
I have 2 sets of the 2015 PFE VisionLine sets that were offered by Lionel last year. This year I pre-ordered 2 more sets, 1 of each set offered. So over the long haul, I have what I need.
