Scan to Network Function

In a bid to remove the paperwork at home, i wanted to invest in a home compact scanner to digitise incoming mail.

I've recently bought myself a new NAS box and was hoping to scan documents directly to this network drive seeing as they will end up being stored here anyway!

This 'Scan to Network' facility appears to be an enterprise idea as i cannot find any home solutions for less than £100. Even the All-In-Ones seem to lack this functionality....

Anyone able to recommend a product?
