I used NP400s interchangeably with the Pentax K10D battery too. No problems, although the Pentax battery has a little more capacity. The Canon batteries I've seen, while similar in form factor, are not compatible with the NP400 terminal layout.
BTW, no name D-LI50 batteries for Pentax K10D, K20D are available from BestBatt.com for $...@. You can get a compact, one-battery travel charger for them from the same source for $18.
