Mobile recording equipment recommendation

Alright, this is probably a longshot given that this is hardly an audio forum, but I’m interested in some new equipment for making field recordings. I’ve been using my much-loved Sony MZ-R50 MD recorder with a good mic, but I’m just not happy with the artifacts and occasional compression effects I get with it.

DAT, HD, Solid State…even a higher quality MD? I’ve already got the (expensive) mics and amps, and I’m not sure which way to go and I’m wondering if anyone has any experience with this stuff or knows of a good source for info? Thanks!

Solid state all the way man. The older Marantz units are decent like this Denon Professional - Professional-grade Audio/Video Recording, Playback and Signal Distribution but I think there are probably newer ones (non-CF) available by now.
