recently my mz-n707 seemed to have lost its recording abilities, and i dont want to spend so much money repairing it, so i am now thinking of getting a new md. If i were to buy one, i would probably choose a hi-md one, but it really confuses with all the models. for now, i have my eyes set on rh10 and nh1 what are the differences between these two? i am not clear of what different models offer, like if they differ in sound quality (priority) , or some other things i dont know of. I don't have real special uses for it, but i want the hi-md to be able to play and edit/record to old standard mds(through optical line in)because i still have empty discs that i would like to record. and also i dont get the reformat thing; do you have to reformat a md to record on it? or does that just give you a bigger space to record? sinnce i still have my mz-n707 that could be used as a player, i would still like to be able to play mds from it. i'm looking for somethin not too expensive, and the rh10 is really costly, so i think its out of the calibre, but i was thinkin about it cuz i kno that i could record on old standard mds. So i would consider other models that could do the same, and maybe have a lower price. i wish i could get some recommendations from ppls, and suggest me some models that i could consider. thanks in advance
