There is a $1000 rebate of the Epson 7900 and only $600 of the Canon ipf6300. Buying from the US ie. B+H won't ship either printer to Ontario, Canada. I tried.
The price difference is that huge right now I can't justify the Canon even it is supposed to be faster, has user replaceable heads and ink and paper costing software, plus some poster thing.
If I buy one roll of paper ($120.00) the retailer will even drop ship it to my door.
Canon has no penetration in the stores I checked here in Ontario, its always Epson. Oh sure they can always order it they say.
Final Tally - Canadian Dollars
Epson 7900 - all inclusive - taxes, shipping, rebate, electronic recycling fee and extra roll of paper - $3222.14
Canon ipf6300 - taxes, electronic recycling fee, rebate, no extra roll of paper, no shipping - $4330.73
Difference - $1108.59 - you can buy quite a bit of ink and/or paper with this difference.
