ah.. the good ol' MD/MP3 debate. For me, anything CD player like is outta the question because of size. I don't care if I can have 1000 songs, thats a pain to sift through if i'm looking to find something specific.
Here's what i've been through:
Rio300 (MP3, 32MB)
Rave2000 (MP3, 64MB)
Sony Deck/Player Combo (MD)
A different sony Player (MD)
Kenwood cd player (CD)
Nomad II (MP3, 64MB)
Sharp MT15 (MD).. this has yet to arrive, bought it from someone here.
For me, I just like the MD technology. And with mp3, 64MB is 1-2hrs, depending on how I compress it. And it actually worked well for me at school, walking around, listening to music... changing every few days.
Why go back to MD? I never really got a chance to make a bunch of discs, and I found recently it would have been very handy. As if I go anywhere w/o a computer (mine specifically), i can't change music on my mp3 player. Yes, the 1x time will be annoying, the reason i got rid of my set in the first place, but if i make some premade ones instead of shuffling 3 discs like i did before (was too keen on the whole mp3 thing at the time), i think it'd be ok. plus, i love them little discs.
Pricewise, I think either one is just as expensive. With the really cool MD's on the very high end, those things are expensive....
