I don't know much about Athena, but their workflow is sweet. Their pricing is different and if you already have an in-house biller; it is rather tough to go with them. The other downside and this is almost a dealbreaker for most EMRs, the demos are good, and the YouTube videos are OK, but there is nothing like kicking the tires. 30 days in a sandbox would be a good start forward given the cost and the committment.
