Well, I've ordered a new K30 to replace my old K200, and am very excitedly (and impatiently) waiting for it to arrive!

In the meantime I've been looking into some accessories, namely batteries. I want to get at least one replacement battery pack, and was wondering if anyone recommends a particular non-Pentax brand to look for. I don't mind paying for an actual Pentax battery if I have to, but if there are quality alternatives at a better price, I'll not going to argue against saving some cash.

I'm also keen to get a AA battery holder as a backup option, as well. Has anyone had any experience using these? I haven't had much luck tracking them down, however I did find a generic-looking model from China on eBay for the exceptional price of seven bucks, including postage. Should I be looking for something a little less, erm, suspect, or is it safe enough to go with something like this?

Any advice is greatly appreciated, guys!
