i think that is a more than a reasonable price. other than the keys, there are only a few custom pieces. $250 is a little steep. the globe? yes. that is worth $230 (which i just bought to build to keep lol so that is why i can justify it). the knockoff i built was a lot of fun.
Yeah, they're both being retired by Lego, so I'm tempted to get them now before they go to the secondary market where the prices will likely be higher.
