I think very highly of Lahey. Total source code, and written in the exacty same way as SBT. TIW doesn't have total source code, not sure about the others. There are various flavors of Lahey, you don't need to spend an arm and a leg.
>My company is looking at our options for BOM and inventory costing software to be used in conjunction with the SBT accounting software. We want something that is customizable and is written in VFP. We are looking at TIW, Lahey, and Everest. Does anybody know of any other packages that fit this bill??
