>Do you know of a good date picker calendar textbox? I tried the one here ( http://leafe.com/dls/vfp ), but it really doesn't look good, though it works well. Should I try to tweak it, or is there something better?

There is always something better - or a customer who demands another version.
Go for extensibility - create a simple interface coupled with a factory so that you can exchange date pickers without problems perhaps even through user-manageble dbf's or ini files.
