I've done a search on both, but these posts are several months old. Obviously looking for the most flawless performance (both caputre AND battery) as well as portability. The mounting doesn't really matter as much since I'm using a GL2 and none seem to exist for that.
I LOVE the Nnovia. It's a great tool. I did a review on it, just finished reviewing the Firestore...but that's where I'll leave it for now. You can find my Nnovia review on the DMN. Nnovia makes the Laird unit.
