$500 for a tin of red paint and a used toothbrush is a bargain.
Jackson Pollock did the same thing with Blue Poles and it is now worth $30 million.
I'd much prefer the Stern mod as its interactive! even spending a little more at least it looks like it belongs to the game and theme. There's some great mod guys out there but there's also a ton of unlicensed crap to and thanks to Stern there making some nice coin. If I bought a WD I'd get the topper for sure and judging by other forums I reckon they will see heaps.
