The VDR will never be updated; it was dropped awhile ago (with good reason, it wasn't a good system, it was impossible to balance out correctly. It was fun, but fun doesn't mean good.)
OK, I don't think you'll ever see my way (that things are priced according to use within their own codex), and I don't see yours either.
So how about this; remove the plasma gun option and replace it with the mega-blasta option from the ork codex?
