Digital BW, The Print

Has anyone tried the Fred Miranda B&W Pro and/or the Power Retouche 
B&W s/w...? I think I read somewhere with the FM when you apply 
filters it causes image degradation and not sure if it works in 16 
bit...? 

Also, I have a few B&W prints that I would like to add a film frame 
edge effect that emulates what can be done in a darkroom... The only 
package I know of is Extensis Photo Frame and was wondering if anyone 
has tried it or know of other apps?  Most of the effects look 
cheeseball, and I guess I could make my own ... 

Thanks in advance
