Okay, so has anyone ever actually come across either somewhere to get those plastic cases? (They are rather convenient...) Or some decent alternative to carry a couple of them safely? Also in response to the comments about the safety or li-io batteries, somewhere else I saw a link for www.batteryuniverse.com, which turned out to be an excellent read, and if you've read this far (I think it took me about an hour to read all 6 pages of "Are the batteries safe? They seem too good to be true. I haven't had any problems with them" comments... then I highly recommend reading about the Li-Io batteries from that website, or even getting the book the site is quoting... How did that work for you? Okay, and now for a slightly off topic, but not really comment. I have an old (stressing the word old) MD player, that I've been using since about 1995, back when they first came out in the US. I am looking to replace it, but haven't seen too much available in the US, since we were mostly all ignorant to such a wonderful device, and they never became the hit they are everywhere else... Any suggestions, I need it to be able to record live, and playback, so not too picky... I have an old (again... very old) mds unit, any news on a Hi-MD unit similar? Again, looking for news, since I don't use Windoze, any idea if Sony will be allowing .ogg files to be played on Hi-MD's? So, I recently purchased the MZ-DH10P which I love so far, but like everyone, am having issues with the battery, and with the charger. Is there a decent solution to actually charging the batteries, or am I just stuck with buying another device to use as a charge cradle? Also, is there anywhere (can't seem to find this specific cable) that I can buy a spare cable, so when I am at other locations, I can use the spare cable to connect to other's computers, or am I stuck with unplugging the cable any time I think I might need it? Okay, one last thing: Is there a way to charge without the charging cradle (again, for when I am at other locations...)? Thanks everybody for your insight and tests on those batteries...
