I recently bought the HP C7280 right before it went on sale for $120 off, so It is a good deal right now. I like the machine, except for the users manual, which doesn't go into much detail or explaination of the features. I had to contact HP and they linked me to an on line PDF file manual that goes into detail, I think, haven't had time to look some things up. I like the wireless operation with my Laptop and it prints very good pictures. I haven't tried the Fax feature, but the scans are good.
I have had and still use the HP PSC 950 for years and still does a great job.
