I have 2 NEFs, the .223 Ultra and .17HMR. Both are very accurate; .75" or better at 100yds. Days they don't group are usually caused by the "nut behind the stock."
Quality? I'm impressed with both rifles. They're inexpensive, to be sure, and from what I've read they do have their share of problems. But in comparison, a friend recently sold his 7mm Mag 700 Remington because of quality issues. No tool marks on the NEFs, and everything locks up great. Brief problem with cases sticking on the .223; 10 min. in front of the TV polishing it by hand cured it.
If you reload, you may have an issue with cases sticking when you go to hot loads -- The cases expand a LOT, and the ejector (if the rifle isn't using an extractor) won't be strong enough to eject. Two solutions: Step down slightly with the loads, or always full-length resize.
If you go to look at them, check the way they lock-up. When closed, you should see no light between the barrel & receiver. Take the forend off the stock and make sure there's no play when closed; if the dealer won't take the forend off, go to another dealer.
Overall, these rifles are more than hunting accurate, and are downright fun off the bench. Benchrest accuracy, if you're pursuing that, is going to requiere a LOT of $$$ for ANY rifle. Because the NEF's need to be taken off the rests between shots, that adds to the variables in accuracy because you'll never seat it the same way twice. But for fun on a budget, I say go for it! I'm happy with mine.
And MERRY CHRISTMAS!!!
