I searched for this topic here, but everything I found was at least a couple years old, so I thought I'd see what the current consensus is. I'm printing out a bunch of pictures for framing, and some of my older ones were taken with Powershot S60. There's the cliche that it's not the equipment, it's the photographer, but that's not true if you want to blow up a 5MP shot to a large format.
I've tried the repeated 110% scaling technique (with and w/o bicubic sharper) with an Unsharp mask after it, and it seems to work pretty well up to about a 4 steps. There seemed to be contradictory comments on here as to whether any specialized plug-ins such as Fractal..something or others provide a genuine benefit. Any advice?

Thanks.

In case it's important, I'm using CS2 now, and I'll be getting CS3Ex soon, but possibly not in time for my deadline.
