I currently use EasyWorship. You can download a trial version to see if it suits your needs. It has KJV in the trial version but the others were not translations we would even use at our church, it wasn't like NIV or NKJV or anything like that. I think the cost of the software is like 250.00 though.
Mediashout is over 100.00 too. I liked it, but their trial version didn't have KJV, and it was a little more complex to teach to the young folks who help me run it. I'm sure they'd catch it pretty quickly, but EasyWorship was a lot easier. Also, Mediashout didn't have the capability to quickly enter or modify songs on the fly like EasyWorship does... but I guess that's not something you would need, anyway.
Those are the only two I have used firsthand. When I went to SisterT's church, her media person was telling me about something called WorshipPro, I think? Anyway, it was only available for Macs but she seemed to think it was head and shoulders above EasyWorship and had just had their Media Ministry outfitted with Macs and was preparing to start using that program.
