I am looking to get a couple things for my MD player. First I need to get another battery and was wondering if the NH-14WM was actually the upgrade for the NH-10WM? Some sights I have found said it is but then some don't have it listed for the RH910. Second can anyone make a recommendation for a good remote for that recorder? Not sure which ones it can use. Thanks for the help guys been out of this scene for a while.
