As per the discussions on this group, the VS model has a much better way
of securing the blades. That may be worth the $15 difference.

Not according to the manual. It has the same socket head screw setup as
the original single speed model.

Here's a post from the discussion I was referring to:

Quality looks good. In particular, in addition to adding variable speed
it seems to have "solved" some of the complaints with the earlier model,
including:
- Raised 'dots' that engage with holes in the attachments, allowing for
positive locking of the attachment which prevents the slipping that
reportedly plagued the regular model which needed the screw to be
wrenched down real tight to avoid slipping
- Pretty quiet -- quieter than a pad sander
- More ergonomic shape
