kall8.com dirt fucking cheap and since I get faxes maybe once a year, perfect. Works fine, website looks like it was pooped out of template monster in 1998 though.
It's 2013. I fax. I Popfax )
Try Popfax.com - I use it, like it, share it. And it's cheap. And comfy. And I even can install it on my mobile. And... shall I continue?)
Ugh, I send at least 1 fax almost every single day. Not sure what you guys all do for a living. But here, I have a shitload of contracts constantly coming in and out.
Either way, I use a fax machine. I find it more convenient to have it just print it out right as its received. Sending is easier too.
