Short Answer: NO. It's absolutely not worth it.
The commercial FN Supreme 98 actions (made in the 1950s), and the pre-64 Winchester Model 70 actions, are superb, and could be had in near excellent condition for half (or less) than the Dakota action.
Frankly, if someone has this kind of money to burn, then I would urge them to please go to the poorest part of their city, look at all of the little kids who don't have winter coats, and think about spending that extra $1,000 by buying 50 coats or so, and passing them out.
