Standard version (not PRO) of SILKYPIX's new Developer Studio 7 is currently on an introductory price campaign. Quite a considerable discount at about $100 off.
The special price is for either a new license or an upgrade from a previous version.
This may be ideal for Fujifilm users wanting to get the best out of their .RAF RAW's (general consensus is that Light Room is not so great with Fujifilm?).
But it's a bit of a steep learning curve - so perhaps not recommended if you don't have much time, and just want to get straight into an intuitive work flow.

The Pro edition is also on sale, but the discount is not as significant. Compare the different versions here
