I bought this set because it was really cheap, and I wanted to check out the theme. When I first saw the Rockmonsters in the LEGO Magazine, I had been excited about the theme, but when I heard about the Miners it just seemed weird. It was cheap, so I bought it along with some other cheap sets were I was trying out some other themes. I got home 2 hours past when I normally go to bed, I built it, and played with it so long that my parents had to send me to bed. I don't know what can be so much fun about a set as simple as this one, but I had a blast playing with it. It caused the entire Power Miners theme to be my favorite ever. I highly recommend this set.
