Better than Marantz 660?

[Alexa]

I have this:

http://www.musiciansbuy.com/Marantz...lash_MP3WAV_recorder_with_Free_PMD660KIT.html
but am looking for suggestions on something similar..but with LESS NOISE.


I would prefer it to be portable..but would look at something less than portable..

I find this one to be noisy when recording single voice tracks.

Thanks!
