I bought an MZ-HNF800 the other day. It's purty. Didn't come with a Hi-MD disc, but the regular ol' ones can be used in "Hi-MD" mode which somewhat more than doubles their capacity if you stick to "SP" (250Mb or so of ATRAC3plus at 256kbps compared to 140Mb or so of ATRAC at 292kbps). But if you want to squeeze it in, ATRAC3plus has a 64kbps mode which is surprisingly good.

Okay, I'll shutup now.
