Recommend me your best

Hello,

I am not much of an expert in home electronics and I was wondering if you can be just a little kind to recommend me the right product for my needs.

You see, I was actually looking for a voice recorder so I can record dictates. I was searching for "audio bugs" because they are small, light and secretive and may become handy one day but then I came across "pen hard-drives" and "mp3 players-recorders" and I thought the latter is better because not only can I record voices but listen to music too downloaded from the internet via my pc.
This is even better for me.

Anyway, now I have come across "mp3 players-recorders" that have their own "internal radio" so now I can listen to music from the radio and record them too aswell as record voices and download music from the internet via my pc !
Recently, I have come across Ipods on ebay and quite frankly I don't understand the difference between the Ipod and an mp3 player-recorder.
I don't have Apple Macintosh but a regular PC running Windows OS.

So may I tell you what I want and you can kindly recomend me the BARGAIN best for my needs ?
I want a small gadget that will:

* allow me to download music to it from my PC's
hard-drive and/or CD
(I want to listen to music and audio files downloaded
from the internet)
* play music and audio files from it's internal
hard-drive/memory
* plays mp3 (better if it plays any other formats too
such as wma)
* play radio (so I can listen to the radio when I am
out on the streets and don't have access to my car
radio or home radio or walkman)
* records voices and sounds near it (via built-in
michrophone so I don't have to attach a michrophone
and speak into it unless I want to attach such)
* records music/voice direct from it's own radio system
* let me attach ear-peace (so I can listen to things
with-out distrubing others near me)
* has replace-able or 'built-in internal"
battery that is rechargeable (so I don't have to
spend money buying batteries every so often when
batteries run-out of charge)
* is small, light-weight (suitable to reside in shirt
pocket or cling to shirt-collar)
* look "un-notice-able" (secretive) so I can secretly
record conversations with persons whom I engage in
conversations.

Please recommend me a low cost, bargain gadget and then recommend me a brand and model on that gadget.
I don't know what this gadget should be (Ipod, Mp3-player-recorder, pen-hdd, anything else which I never heard of, etc.).

Thank You
