I just bought the cheapest ones and they were always accurate for me, both when it was positive and negative. Keep in mind the well-known brands are just more expensive because of advertising. It's the same test.
I like the dollar store ones, but I also like the Answers strips (there's like a pack of 5 in a box). I specifically like those because I liked being able to clearly compare them side by side...
I used first response 6 times because I wasn't 100% trusting the faint second line I kept getting. Someone here recommended I pick up a digital for peace of mind (I got clear blue easy I think) and they were sooo right. It felt so good to see the word pregnant and not have to worry about lines!!
