Email to fax

I was wondering if anyone uses the online email to fax services out there, where you send a fax by email and it gets converted to a fax at the recipient's side, and a fax from them gets converted to an email at your end.

I send & receive faxes very rarely, but want one just in case - so a per per usage plan would be fine. Ideally I'd like a south Dublin fax number, only so it is not too different to my landline number.

I've found a good few such services online, but some of their prices can be hard to find out and I want to be able to confirm my fax number sooner rather than later.

thanks in advance.
