Alternative ...Battery Grip??

[Bustoner]

I saw on the Bay they are selling from China a Grip Battery at only 36€ and free shipment, good difference from the original one (about 160€)

Has anyone ever tried it?

Sure, but down there is a compatibility list, and even Sigma SD14 is there.
I ask to the seller, and no reply...

....wish already someone have tried it to tell us...

If it's compatible with Pentax or if it looks like the one in the picture, it's not compatible with Sigma. Pentax has the contact pins under the camera body and sigma has them inside the battery compartment. But, there are indeed some picture in a slide on the left of the page with some picture that look promising but perhaps it will only work with the trigger cable.
You could give it a try and if it doesn't work, I'm sure you'll find someone with a Pentax to sell it to for 36 euros.
