After watching David Forrest's Trickery DVD, there's a really amazing Coin through Deck effect that I want to add to my table hopping routine.
Only problem is that since he uses coins from over in the U.K/Scotland which are magnetic, while US quarters are not.

While I was searching through Penguin I've found two different Steel Core Quarters, so I was hoping someone could tell me which of the two would be a better purchase.

Steel Core Quarter by Tango. for $9.75

Steel Core Quarter by Chazpro, creators of the Raven. for $15.00

Any insight and help would be greatly appreciated.

I can't say from experience with this specific product, but I would think that the makers of the Raven would make a quarter that would work well with their product and ones like it...

That's all I needed to know, thank you.

I can't tell the difference in quality between my Tango coins and my Chazpro. Either should be fine.
