Quoted from Warzard:

If you want to save money for so much useless complicated process then use decals, playfield protector reverse printed with white wood instead of stupid playfield, use plastic when you can instead of solid metal, don’t make ramps and scoop and toys (useless) and use the cheapest and less powerfull system: the rapsery py because at the end who cares, don’t spend too much time in testing with new mecanics...
Then you’re ready to reinvent the new Wall Mart pinball but... wait ... stick it a collector decal, say it’s limited and put a price for the richest of us (who own at at least 10 pins with a lot unplayed) and there we go: you’re now one legitimate actor of this industry.
Not that bad.
