This is probably old news, but there are a lot ,ore than 3 sets on offer in this series
there is also 3 series in the figure sets and a special set with all the doctors in it.
Now as far as quality goes, it's okay, though on the console set, which was the biggest, I needed to add bricks to make it stronger, other than that it's ok. The daleks and cyberman figures look excellent, but the figures themselves are not lego mini figure look a likes, so remember this when you buy them.
