camsna - thanks for the tip, I'll take a look.
MrMarkIII - yeah, I get it - that's why I asked. Most of the solutions I am familiar with (from the camera bag side) are expensive. (E.g. Pelican cases makes some completely configurable hard-shell cases with removable foam blocks for custom sizing. They are not cheap.) If you have other suggestions, chime in.
Thanks,
Dave
