Strange. Currently, Amazon (in the US) has the grip selling for 200 dollars. That is a huge difference...

My experience with off brand batteries has been moderately good. I bought from Deal Extreme and the batteries I got have not caught fire or caused any issues with my camera, however, they last about three quarters as long as the one that came with my camera. This is not an issue with shooting photographs, but if I do much video, they will drop to unusable levels fairly quickly.

You are probably pretty safe with off brand batteries. Remember that Pentax doesn't actually make their own batteries either. However, the quality control on their batteries is probably better. I find that my off brand batteries don't last quite as long and stopping holding a charge quicker than do the name brand batteries.

Well, there is some engineering to go into the design to make certain that it fits the camera well, is good ergonomically and in this case can take AA batteries. But finally, camera companies sell the camera bodies relatively cheaply and expect to make their money on accessories -- grips, flashes, and lenses.

Clearly the issue is exactly the fact that it is a copy and a fairly exact copy, not that there is a third party grip out there. Most third party items are made by backwards engineering and therefore lose a little to the brand name products. Sigma does not pay licensing fees to Pentax/Canon/Nikon for using their lens mount, at the same time a) They come up with their lens designs themselves and b) Their lenses may not function as well with a given camera as a result.
In general, China has not been protective of patents and other property rights at all. Whether this is artistic infringement (selling pirated DVDs) or stealing other designs, it is important to protect these things. It really is the principle of the thing, not just the item itself.

Falconeye is right. It doesn't matter what the product is -- Nike Shocks, an I Pod, or a Pentax grip; if someone copies it and sells a direct reproduction, it is illegal. Each company needs to start from scratch with these items, not just buy one and then copy it. Sure, it is cheaper, but imagine if you are in the shoes of the one being copied.
The issue really isn't the danger, it is the intellectual property rights of someone who spent time to design a product, only to have it stolen. China needs to clean up its act. If a US company started doing this to a German company or vice versa, they would be shut down yesterday.
