thanks to all for the advice about availability of an external battery case for the Sony MZR55. A friend of mine did find it in London ( in fact, it is somewhere in Harrow, Londoners might had a better knowledge of location); it cost me a 10 UKpounds ( 15 $, I think). P.S. I'm using 2 AA NiMh rechargeable of 1500 MAh in it, and its performance are amazing! They're refusing to drain out after several hours of recording and playback ( AA only, with the gumstick battery out!!) It is well worth to invest in something like this, because I did find how non-rechargeable alkaline AA's are going off a lot faster! ----------------------------------------------------------------- To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]
