Paying for good eggs is probably worth it, but whether organic eggs are good is up for debate, it's going to vary from source to source.
Good eggs are raised on nutritious food, with access to grass, bugs, sunlight, as free from stress as possible and ideally without any chemical pesticides/antibiotics/hormones in their diet. Organic will guarantee the last facet of the above, but it needn't have any impact on the others. It's entirely possible (indeed this applies for the organic eggs in my supermarket) to feed chickens on organic corn or soy, it's difficult to imagine that this would bring that much benefit.
This is borne out by this study: organic eggs contained slightly less omega 3 than conventional eggs (1.34 versus 1.36) at a ratio of 1.34:15 (!) omega 3:6 (admittedly a better ratio than conventional though). Eggs might be nutritious in lots of ways, but if you're after balancing your omega 3 levels then you'd better look to fish. Omega 3 eggs (likely fed on flax or seaweed) conversely, contained 6.57g omega-3 (about 5 times more) at a ratio of 6.57:14.8.
The benefits of pastured eggs have been shown here, they contained 0.66g omega-3 per 100g compared to 0.22 for conventional eggs. They also contained 4-5 times more vitamin D and about 50% more vitamin A.
On the question of eggs in general, even the cheaper ones aren't good value for fat/protein compared to cheaper cuts of meat (but then I never buy grass-fed), I eat them for the various nutrients that you get from yolks that you don't really get from muscle meat: choline, K2, vitamin D and 'precursor molecules'.
