Their quality control seems to be hit or miss. Every so often I hear about someone getting a bad one, often even after being sent back they still break down. I hear it far too often to trust them. If not checking them for quality is how Taurus gets their prices down, I'd rather pay more for one that works. For that matter Taurus doesn't even have the lowest prices for budget guns, so I don't see the draw there either.
