I got myself a md player just two days ago (the Sony 410 model) and thus far I am very happy with the sound quality. It drives my mx500 very well, and has more than enough juice to make my grado sr80 sound good ( for quiet environments: found that 17/30 volume is adequate/enough for comfortable listening volume). Even though it uses atrac LP2, some sort of Sony compression im still learning more about,
I already have a harddrive based mp3 player, it's a 10 gig Treo, but the connectors inside the headphone out is going bad. I thought about getting a flash based mp3 player, but saw that it's too costly for the amount of memory i get.
Compared to a $30 64 or 128mb flash card, a $2 80min (or 160min when LP2 is used) is a better deal in my opinion.
Yeah, found some some great SHARP MD-MT90 pictures:

I'm not sure if i will kick myself in the future, because the 410 sony md model doesnt come with any line ins (like optical), besides the usb. But hey, Good Guys have a $30 rebate for it till the mid/end of December.
Let me reiterate: I am impressed by the sound quality from the md.
And yeah, handling the md disc is pretty cool too.
