WBT Power Bridges or Dayton Jumpers?

Doh! I just realized after months of testing that neither of my 2 pairs of Monitor Audio speakers that I bought here on Audiogon has their brass jumper bridges between their two sets of binding posts. Imagine the embarrasment/surprise finding out all this time I have been neglecting the bottom mid-woofer of my S10's. Better late than never, though, I suppose. The guy who I bought them from didn't have them bi-wired either...

So now, I'm faced with the task of trying to find suitable speaker jumpers. Just so you know, I've already bought 2 pairs of WBT 0725Cu's for $17 each, way too much for little pieces of copper in my opinion. This thread is about better options.

I tried looking for the original brass strips; no luck. I've read that pure copper does better than the stock brass ones, only to discover they were advertising these flimsy copper strips for $500 each!! True audiophile gear, I'd say (sarcasm...) Then I came about 1"-2" jumper cables from various cable companies like Cardas... $100+! Finally, there are these little gadgets like the ones listed in the title, and another by Cardas for about $15. I can't help but wonder if these things would fit binding posts of all different sizes, but I'll find out in 2 days when it ships.

Do you guys have any hints?
