You'd probably have a pretty steep learning curve as although I would think it'll do pretty much anything PS will do, it'll do it differently. I use PSP (x6 is the version I'm stuck with till I upgrade the pc), but I've used PSP all my life. I wouldn't change to PS because I know how PSP works. While you can find tutorials for just about anything related to LR/PS, it's harder to find PSP tutorials, as LR/PS has become the 'standard'. I have sometimes found myself looking at stuff written for PS then trying to work out which tools/processes to use in PSP. But if it's only £45, why not just get it and try it? Just don't get rid of PS yet.
