Preamp or "U" jumpers: where to buy, choices?


Hi guys,
I want to replace the "u" jumpers on the back of my inegrated amp, the piece that you would remove to add a seperate amp. I have only found one company that makes them, Audioquest, at a price $40. I'm not sure why, but this price strikes me as awfully high for what these things actually are.
Does anyone know of other companies that manufacture these?
If so, is this price high, or relatively normal?
Thanks, Jb3

From my understanding, the Cable Company makes U-bar replacments as well. I have used both the Audioquest and Tara Labs, I preferred the Tara.

Regards,
Funny how these threads pop back up. Since I posted this I had them made for me by Signal Cable. Since its basically just a short IC Frank made me a pair for $25, basically a very short Analog2. They work great, a good tweak for the money.
