>MSDN Library, hmm... as I understand it, I get an MSDN library subscription with Visual Studio Pro, which is $458.48 for a competitive version upgrade. Maybe I should con my employer into getting me devstudio. I don't use any other languages in DevStudio, and don't have a specific need for fancy components or anything, so I don't know offhand how to justify the extra $230 or so. Also, I'm not completely sure that I can use that upgrade if I have only VFP3. Have you any words of wisdom on the matter?

As long as you have 1 or more of the earlier versions of any component of VisualStudio, you can upgrade to VS6. Even having only VFP3 qualifies you for the upgrade to VS6.
