It seems that there is a consensus to say that it's not the most appealing WV set, because it's not a house, and so not the best investement you can do.
I respectfully disagree with that point of view.
Because you can build a WV and miss a house... but can you have a village without this set ? IMHO it's like the cement of a wall.
And about the scale, I think it's ok. A real carrousel is big in size, nearly as big as a small house. I'm ok with the size of it (but I admit there are only 4 places for kids and that's not a lot). BTW the other existing carrousel is the 10196 carousel and it's faaaar too big.
So overall, yes, this set may be not the most beautiful WV set, but a lot of people will "need" it... and of course, it's an "official" winter village set.
That's why I believe that this set has a great investment potential. It adds some living to a winter village, even more if you motorize it.
