Seeking your opinion. As Staples is having some pretty good deals on printers, I am looking for feedback on choosing one of these two. The Canon Pixma MX860 and HP OfficeJet Pro 8500. With the trade-in of my printer combined with the instant savings, I can get the Canon for $100 or the HP for $150. The only substantial difference I see is the HP is almost 4x faster at prints. I have had Epson products for years but I have not been happy with them since OS X came out. I have always like HP, but have heard Canon works well with Mac as well. Any thoughts are appreciated!
