We were surprised to find nice chocolate at discount grocer Aldi, of all places. They actually have two "store brands" - Moser Roth and Choceur. Moser Roth is definitely the better of the two, and is made in Germany.
The 70% has a lot going for it, though not everyone will like it. The flavors are very subtle, none of the obvious fruitiness that a lot of better dark chocolates have. Because of that, some people will probably find it bland. I quite liked it, though - it's not as bitter as many 70%s while also not being sweeter than you'd expect, and the predominant flavor seems to be pure cocoa. It's nice and crisp, a lovely texture.
After just eating it, we also tried baking with it. We tried making a flourless chocolate cake using this recipe, and the massive amounts of butter and egg just totally overpowered the subtle flavor of the chocolate. The recipe needs something bolder and a bit lower-percentage, while the chocolate needs to be used only in recipes that really let it shine rather than burying it. Perhaps in Alice Medrich's "Albert's Mousse" from Bittersweet.
Overall, at $1.30 for a 4.4-oz bar, this is a great deal for good 70% chocolate. It's clearly not as good as bars that cost 4 times that, but it's at least as good as many that cost twice that. There is also an 85% available, milk chocolate with toffee, and a few other varieties.
