Canon Pixma MP520 or MP530? Wish to use for photo and office apps.?

I've checked out cnet reviews for both models, but I have not bought a printer in a long time, and I am not sure whether these models will fit my needs, have convenient and inexpensive cartridge replacement, ability to print on photo paper and office printer paper equally well, etc. etc. Anyone have experience with these models or recommendations for my printing needs (office printing, documents, online postage, high resolution photo printing for cards and brochures, as well as standalone photo quality prints on glossy paper, etc.)?

(also, I have never had a fax machine on a printer before. it might come in handy since there are no real public fax stations around here, but do I really need this if I have email-mainly communications business-wise?)
