My father-in-law has the third NULA every built in 30-06. So, I have been around one a good bit as that is his "do almost anything" gun (which says a lot since he literally has 100s).
Since there seems to be several gun manufacturers offering lightweight rifles in the more common calibers, I think the best value is a NULA of large or wildcat caliber.
Are you buying as a gun collector, hunter, etc.?
