I use the Epson 830, which I purchased a year or so ago.
Like yourself my printing is mostly used for business and posters for organizations, with the occasional family photo.
Text is very clear and sharp, clip-art is also bright with realistic colours, but the best by far is high resolution photo printing. Using a cheap 140gm glossy paper the photo quality is superb. I would recommend this printer to anyone.
It is a great workhorse.
P.S. another good thing going for it click here Thee are the only cartridges that i have used on my 830, since the originals were finished. They are every bit as good as, and have at least the same amount of ink.
