I was gonna leave this as a response to a comment from Joseph on the last post, but I had some issues posting links in the comments box and I figured other people might also be looking for this info.
So, if you too are looking for a low cost solution to for a Digital Recorder or a DIY Boom Pole peep the below:
IPOD RECORDER ATTACHMENTS
I have an attachment that connects to my video iPod that records CD quality (44.1KHz, 16-bit stereo) audio and has a connection for an external mic. I use it as is for my podcast and I've been very happy with the recording quality.
Check it out here:
Belkin Tunetalk Stereo
There's also this one, which I'm not familiar with, but it got a good review as well:
Xtreme Mac Micro Memo
Apart from these, just sniff around the web for digital recorders, if you're looking for a stand-alone recorder.
