I got the Ferris Wheel (10247) as a birthday present this year and also built the Fairground Mixer (10244) just recently. The only amusement ride I missed was the Grand Carousel (10196) since I was still in my dark ages back then und now it's way too expensive to buy this set.
But that didn't stop me. I had to build it: I used a different colour scheme and made some changes on the roof. I also didn't like the jumper horses and replaced them by two pirate ships, two cars, two locomotives and two propeller aircrafts.
