Can someone give me some feedback on any of these products? We are considering replication for our MSSQL servers as part of our redundancy plans. I just started poking around for solutions so any feedback is appreciated.

1. Resonate softwares dbDispatch
2.CA XOsofts WANSyncHA SQL
3. Sybase replication Agent for MSSQL ( We are a Sybase shop and are experienced with Sybase replication and understand how it works but have no experience implementing there MSSQL solution so if anybody has experience good/bad that would be of interest)

Any other solutions that do not require a special hardware upgrade is also of interest.

Thank you
Joe Buhl
