I have been playing with Photomatix in trial form and I am now ready to buy.
Problem!! Do I buy the full pro version or a plug-in.

I shoot Canon RAW and process n Aperture2 and final adjustments in CS3

There is available a Aperture2 & CS3 plug-in at a lower price.

Does anyone know what the difference is, if any, between the full ver and a plug-in?
