I have the vcom partition manager and it has served me well. Switched to it when partition magic let me down, simply because vcom had a special at the time. It comes with boot manager etc.
I just bought the paragon "disk manager" (on special, 49.99 for 3 licenses) and it looks pretty good. Contains a partition manager, partition backup tool and boot manager and supposedly some defrag function. I had never really tried their tool and on first look it looks pretty good - comes with restore CDs images both for normal windows but also for the corporate recovery options. I went to the site interested in the backup tool but when i saw this on special I bought this. Will post notes when I have tried some more.
