Hey guys......i just need the top most differences. I read lots, but someone must have some practical experience.. thanx

New to the website - and want to buy a new sony minidisc player/recorder. I have a R900 for many years now. Got it in Japan....but time to upgrade. I did preform a search as well, but no luck. I need to know the differences between each of the models so I can make the est decision. After that, need to find a place to buy it. Also looking for a site where I can compare each model side by side in english(if possible) thanks in advance.
