Sync Tool - Best? (Filemaker Go 12 sync to MS SQL Server 8

[ruhlanma]

Hi all.  I'm looking for recommendations for the best sync tool available to sync between an app on iPad (FM12) and SQL Server 8. 

 

I see Mirrorsync2 and it appears to be the hot prospect.  But I'd like to know whether it really is as good as it states, or are there better options.  I'm looking for simplicity for the users.  A simple single click by the user to perform a sync periodically.

 

Thanks in advance for any and all suggestions/comments.
