As it is a build it yourself, flat pack pinball, I really believe the title will be LEGO.
Also they are constantly having anniversaries for something and LEGO has a GLOBAL appeal?
My money is on LEGO for sure. Chinese go nuts for it too.

Let me make a clarification here.

The run I am budgeting for is 1750 fully assembled, finished units + 250 kits = 2000 total

MOST - almost ALL - will be finished, fully assembled machines

At this stage there will be NO L.E.'s or "special" models - they will ALL be identical including the kits.

I do intend to have available add-on extras such as shaker motor, topper and other extras.

As for Lego - not a bad guess but maybe it should be "KLEGO" or "REGGO" (said with a Chinese/English twang)
