It depends on how much it costs. I needed this for awhile. My startup sends faxes from the internet (http://www.hellofax.com). We need to convert files from 40 some different file types to PDF before we send it to the fax server. There were other converters out there, but they were limited in the number of file types that they convert. So, we are now paying $30+ dollars a month for a Windows server at Rackspace to do it. So, if you can convert a ton of different file types, we would have definitely been a customer.
