Hi Hugh
There is no risk that the GL will be out of step with the AP listing if all you do after unposting is to edit the description and then immediately re-post.
Toolkit for Adagio is available for sale by individual function. So although the retail price for the full module is $1,495, you can buy one function for $495 and each subsequent function for $195, until you accumulate enough functions to own the whole works. This does not include the annual Upgrade Plan, which is essentially mandatory if you want to use Toolkit in the future. Your Adagio consultant may have different figures; I am only detailing the retail price.
