rejuvenate

I've been doing some online research. First off my needs: I am travelling for a couple of weeks to Scotland/Ireland, and would like a MD recorder with good battery life. I do have a charger for AA batteries with all the appropriate plug converters. I plan to: 1) listen to mp3's on the long plane trip to the UK. 2) make some recordings of local musicians in pubs. (probably around 6 hours total). 3) listen to mp3's on the plane trip back from the UK 4) Over many years to come make recordings of local sessions. I'm looking for a recorder/player in the $150 to $250 range. So here's what I have found out so far: Sony mz-rh910 Hi-MD format means less discs to organize. Nice to have but I can manage 10 regular MD discs with no problems. uploading mp3's direct to the rh910 seems to be a great plus. It looks like the internal gumstick battery is upgrade-able. Somewhere on this forum I read the quality of this unit is much better than the older sony's with regard to recording. Is the recording functionality going to be sufficient for quieter settings (folk music)? Would I need an adapter to get AC power in the UK for this? Sony mz-b10 The 2 AA battery power source is what caught my attention on this one. I can charge AA batteries on the road easily. But will the internal microphone be sufficient, or will I really want to get an external microphone (thus bumping up the cost). It is also a little bit larger in physical size (but maybe not compared to the other units with the external battery pack) Sharp md-mt280 The only real question I have for this one is about the internal battery. I don't see it listed anywhere as upgradeable to the Sony NH-14WM or other battery. Owners seem to be really pleased with the recording capabilities of this model, particularly the sync-recording which apparently doesn't get fooled by quiet sections of recording as easily as the sony brand. -- So here's my thinking at the moment: If the gumstick battery for the Sharp md-mt280 is upgrade-able, I think that's the model to get (or alternatively if it can recharge in the UK with a simple adapter). I say this because 1) the recording capabilities seem much better for my situation, and 2) it's less expensive, allowing me to put money towards a better microphone Does anyone have any info on the Sharp internal battery? Or does anyone have other reccomendations? Thanks for any info!
