One of the Profs at the Uni said the latest version is an improvement on others, and he's happy with using it. I haven't tried it myself.
With RSI I would suspect its worth a try, heard its v painful.
Would you be able to try it out with amazon, 30 days money back apply on software?
Alternatively, would your uni have a version you could have as a student. I bought a few things i later realised i could have gone for free :-s so worth checking out.
Hope you get it free and it works for you (up) Chuff
