Pages, Nisus Writer Express or AN Other?

Hi all,

I need a basic word processor for the Mac. It doesn't need to have all the bells and whistles, as it's only for the occasional letter. It will, however, need to support all the various files that I have built up over the years on a Windows PC. For the most past, these are .doc and .rtf files.

I've downloaded the trial version of Nisus Writer Express, and that seems ideal (yes, I know that means I should probably stop my search there!), but at $45 the price seems a little steep for my basic needs.

Pages is less than half the price, so I am wondering if that would do all that I want, whilst also being as accessible and easy to use as Nisus.

Has anybody tried the 2? Or perhaps can suggest another option?

Thanks
