A lot of the custom action manufacturers you're probably looking into are more or less on the same level of quality and accuracy. Maybe consider buying from a local gunsmith or company. You don't have to worry about mailing parts or shipping time, you can go in and shake a hand and build a relationship with said company. I shot NF this year and I was surprised at how many single shot rifles or single feeding was being done. It definitely isn't a deal breaker time wise, I prefer a repeater myself, cause it makes a rifle more usable for other matches or training, hunting, etc.
