Hi Samantha,
Ever thought of simply using fax software?
You install it on your PC and leave your PC switched on. When a fax comes in your PC answers the call (exactly the same as a fax machine would) but instead of printing the blury pages it stores them and prints them when you want them.
The software also allows you to send faxes. You select the document you want to send, enter the phone number and press send - similar to sending an email.
Much cheaper then a fax machine, takes up no room AND it stores your faxes electronically.
