Quoted from lordloss:

Why add more instead of lowering price?

Quoted from PinMonk:

This set of 6 Jetsons figurines is $20. Easy way to dress up the playfield with a few of these, and there are more than 250 sets out there to buy up.

Quoted from PinMonk:

Custom figures are expensive since they EACH need an injection mold made and each also need individual approval from the licensor. These are already made and approved and are plenty good enough quality for the machine, matching some of the off the shelf toys Stern has used before. Licensed properties are not as easy to handle as you may think if you've never done it.
Besides, these are inexpensive and available now in quantity. I'm not saying these are the ONLY thing to add, but if there's a budget of say $200 per machine to improve it, these, real drop target banks to replace the standups, and a few other easy things would be money well spent and drastically help the visual of the game. If I were doing it, I'd put an exit at the bottom side of the ramp above the pops that either dropped into the pops (think walk the plank on Pirates) or doubled back parallel to the "up" part and exited by dropping onto the PF at the Elroy point to the right of the entrance. That would add some relatively easy interest to the ramp shot.
