What to consider monochrome laser printer duplex suggestion?

Hello,

HI 

my use will be home use for text . windows user 

I do need the duplex function(print 2 sides of a sheet)

i want it to be cheap to operate and maintain and not to expensive to buy new

not an expert but i feel like the printer has to offer the possibility to choose dpi dot per inch because low dpi still allows to be read and saves a lot!

not an expert but maybe a high yield capacity toner is better? not sure  im waiting for your suggestions .

i dont need wireless nor cell phone connect.

i dont need color

i dont need the fax scanner

any brand to prefer or avoid?

I will buy through internet probably amazon please explain me what i need to consider and also if you have good suggestions it will be appreciated.

thanks
