I have been looking into software for out outpatient pharmacy as well, but we are much, much slower so our needs are different. I have demos/ quotes out with WinRx, WinPharm, and PioneerRx. So far PioneerRx has been the best looking with a nice quote. Their 340b management suite is very nice (don't know if you are a DSH or not). QS/1 is supposed to be the industry leader, but I was less than impressed with the system and the costs were astronomical. We are hoping to make a decision in the next month or two.
Avoid Visual SuperScript like the plague. It is our current system and it is terrible. Buggy, crashing almost every day, slow, hard to use, with almost non-existent support.
