OKI and Ricoh tend to target business, and don't concern themselves with the consumer segment. I bought my Oki B431DN on sale for $225. Based on my experience with OKI, I expect it to last forever.When I think about how I calculated my cost per page (one of the reasons I chose the printer I did), I agree with the author that there isn't a great way to calculate an estimate. It really depends on your printing needs. Factors I used: M1) minimum I could spend for the features I wanted. T1) 3 years - I always use 3 years as a payback period. P1 )Pages I expect to print over three years. C1) Printer cost C2) Cost of printer supplies (excluding paper) for P1. Cost per page: ((C1-M1)+C2)/P1I agree. I had an Oki years ago and loved it. I'm sure politics are not involved in the selection criteria for choosing hardware for evaluation - maybe they choose the largest sellers? So how would OKI or Ricoh become big sellers if they never get on lists like this?5teelspy :I'm always disappointed when brands like Ricoh and Okidata are routinely omitted from these reviews.
