Since you haven’t get the SL Mk3 yet, I would suggest that you have a look at my own script here:
If you open the pdf file at the bottom of this post, you can see what’s included, and then judge if it’s worth it.
Furthermore, note that for controlling VSTs, you can always use it without even the DAW integration, by assigning its knobs/faders/buttons to VSTs using their midi learn options when available.
