Hi Guys N' Gals. Yesterday I purchased a Sony DCR-HC45E camcorder in preparation for a trip to New York in the coming weeks. I have just been flicking through the instruction book and found out that the run time for the battery is 45 minutes (typical recording time). Obviously while we're out of the hotel we don't want to be heading back and forth to recharge so I would like a second, spare battery. The instruction book list the following battery models: NP-FH30 (supplied) NP-FH50 NP-FH70 NP-FH100 Searching online it's obvious that these things are not cheap at all, so my question is this: a) Will I be ok to use an unbranded battery (if such a thing exists) b) Where is the best (re CHEAPEST) place to buy such an item?, would I be better waiting till in the USA to buy? Obviously the more I can get for my money the better. Thanks in advance for any help/advice/tips offered. Red Devil.
