That's because you have money to burn, and I have to beg my relatives for scraps.
To be honest, I still have a functioning old Toshiba, I was given an HP3300 which has it included and being I am the computer guy among my friends, I get all their throw aways to give to those who need them.
You probably know someone with a bubble jet fax.
They on sale went for $0 at times and for the fax function alone you can find them usable even when the ink-jet part is broken.
So, if you want a freebie fax, try to get someones old ink-jet fax, they are everywhere. Ask a friend if you need one.
