One thing to keep in mind is that Wonka LE has a high quality metallic type finish powder coat. This type of power coat is of higher quality then the baked on enamel look used on Dialed In LE and the rather cheap looking BBQ black paint finish on Pirates LE. I would value the Wonka LE powder coat at $300 - $400 (includes wireforms), add another $300 for the invisiglass, $150 for the shaker motor, add another $50 (at least) for the external volume control and that's $800 right there. Price difference at that point between the SE and LE is $1100 - $1200. That's still a good chunk of change but something to consider.
Here's a video showing the Wonka SE and LE Wonkavator area. The Wonkavator is a cool toy but I wish it would have featured detailed 3D molds versus being mostly pieces of clear plastic and bare metal. The SE area does seem bare though after looking at the LE, especially when the Wonkavator toy lights up.
