Yes we actually funded development of the voice feedback plugin:
Older recorders for Moodle tended to use Java, since Java suffered security issues it has become a nightmare.
Poodll uses flash / html 5 which works a lot better and works on ipads / iphones. One caveat is that my ipad chooses to upload video MP4 when recording "voice" but that is down to the device not Poodll.
Its not perfect, there area few things that could be polished and improved, and I am sure over time that will happen, but overall they are a well thought out set of plugins.
The look and feel of the players is more geared toward a school than say a Univeristy or corporate use, but you can swap these out if you need to.
One of the best things is that it is highly configurable, for example we had an issue with the gain in the flash recorder, there is an admin setting to control that so you can tweak your recorder for the best results.
We found the local recording in Flash did not work well and sometimes lost recordings, it is much better to use the Red5 server. We still use Poodll Tokyo Red5 which Justin makes freely available but he also provides his java app and instructions for setting up your own Red5 server which we will do at some point.
Poodll was the only option I found for what we wanted, which is why we chose to fund extension of those plugins.
On a side note I think a "Poodll Anywhere" feature will be added in the not to distant future which would add a recorder icon directly in TinyMCE allowing you to add audio with a single click from the text editor, that would allow things like threaded voice boards using Moodles standard forums.
One thing I would add is that we are using Moodle 2.4.5, I have not tested this on 2.5 but guess Justin has.
So, yes I would recommend them and no there is nothing else I would recommend over them, and I spent a lot of time looking!
