The NSRCG offers
1) Smartlink 2s for 3500 and essence of .5
But there's a heading marked
2) Smartlink Subsystems, with the four components listed individually.
Is #1 for the whole get-up, and #2 if I'm buying it piecemeal (for example if I already have the image link)
or do I need *both* #1 and all four items in #2?
