Steve,
My partner and I actually developed a simple online voice recorder awhile back because there didn't seem to be any quick, easy, and cheap solutions on the market. (And the ones like odeo didn't work)
Because of other business commitments and market factors we haven't done much with it.
But it works great for simple voice recordings (has for over 4 years), and with the actual record-and-play cost of those little mp3 files, IMHO anybody that shells out a monthly fee is getting ripped.
Anyway, you might want to try
