I have seen, a number of very nicely made, pre-war (II) Belgian guild guns, all neutral. Own one, too. Typically they are light weight, all-day-carry field guns. As to being economy guns, I am usually shocked at the prices - if you buy for quality, I suppose they are reasonable, but if you are after a name, they just don't have one.

The rugged old Beretta Silver Hawks, as LBrown noted, are neutral.
