Well time is money. If you spent 100 hours working on replication in VFP (I doubt you'd have much to show for it after 100 hours, but it's a nice round number) at $50/hour that's $5,000 in programming time. I think that's a very conservative estimate. I think the unlimited user license of SQL server is about $27,000. I'd be surprised if you could write a reliable, flexible replication tool in VFP for twice that even if you only used one of the many approaches SQL Server offers.
