I just came back from a 3 day course on the Accpac Pro series 7.2. All VFP. I can tell you that I think Accpac (use to be sbt) has finally gotten it right. You can poke holes in anyone's work, but the framework they have built and are now using is very good. Also, version 7.2 will work with VFP, MS Sql or DB2. I would recommend taking a good look at it.
