I've already drummed up some support for the RAW Developer from Iridient Digital - back then it was still version 1.2. The new version has definitely become much more rounded and I really like it during my first tests. And even if it's not the fastest converter - it's definitely one of the most powerful. Together with a good image browser like iView Media Pro, it's definitely a more cost-effective and resource-saving alternative to Aperture.
