wp-o-matic here also, I've read a lot of people use feedwordpress also. I tried fwp but there was/is an error in .993 that disables some of the dashboard, widget functions and causes problems with placing images in posts. There was a thread on the developer website about but the last I read it still wasn't fixed.
I have it deactivated on a couple of my blogs and I haven't got the "upgrade plug-in" notice in the plug-in dashboard.
