Quoted from Vdrums:Is the answer "the cheapest one?"
They all look very close from the pics... At least on my iPhone.
I have all three on my games now. The glass price is near the same for all three. The shipping is not. For me I saved $$$ going with http://www.marcospecialties.com/pinball-parts/502-6845-00. The problem is that they can't keep it in stock. I bought four pieces and the total shipping was $9.99. Great shipping price.
