The 3 tier Stern sales model system is simple and very effective.

Some people like the value for money Pro which plays fast and is always priced well.
The LE is always top dollar but you get exclusitivity and have something most people want but couldn't buy because they missed the very quick timeline or didn't have enough $.
The Premium is for someone who wants the Playfield features of the LE and a mix of the Pro and LE on some of the other features.
Funnily enough, in Australia if u buy a Premium, you probably have a rarer machine than those who purchased the Pro or LE.

This system is just like Fords car sales model when I grew up around factory six or V8 models.
Ford Falcon, Ford Fairmont Ghia then Ford Fairlane. OR
Holden Commodore, Holden Calais and Holden Stateman.
But divide the car sales numbers by 1000 and u have the real pinball sales type numbers.

Stern are on a winner with this model cause we see collectors all over Australia with each of the pinny models.
Great things for 2015.
Even JJP has its base model, it's LE model and its Premium 75th Anniversary Premium model.

As Gary Stern said "nothing makes a statement like a Pinball Machine".
The look on people's faces when they walk into a games room says it all.
