My print ratio is probably around 20 5x7's to every one 8x10. I love the smaller print size, but if I feel one negative is exceptional I will print up in size, even as large as 11x14. I run through a box of 500 sheets of 5x7 about every six months, including what my kids use up, so maybe close to 1000 sheets a year, and maybe 150-200 sheets of 8x10 per year. I buy the cheapest 5x7 VC/RC I can find and spend on quality 8x10 paper
