Quoted from Eskaybee:I've never ordered the balls from nifty so not sure how they are. The cascade premium ones are $3.50 a pop which is a pretty hefty pinball price. I'm curious how they compare to the pbl ultra gloss ones. I may have to pick up a pack of 4 to try on my SM.

They get as low as $2.28 in packs of 7. They get progressively less expensive when you buy more than 1
