Yeah approx $400 for a pair. Mainly chip shortage messiness, I think I can get the cost down to less than $200 a pair in April 2023.

Regarding VSDL, never used it myself; I guess it would come down to space/power considerations. I haven't seen VDSL used much in the industrial automation, single pair ethernet seems to be the preferred choice.

Long range networking is a very overcrowded market. You need something that is either really good or really cheap.
