First, welcome to the Toyark!

Second, the listing is actually for an older set (#7237) from 2005. It's OOP, hence the price. There are newer and far more affordable versions available. In fact, for roughly the same price as that set, you could get a couple of the newer sets and still have all the features of the first one. I would recommend these:

Set #7498: Amazon.com: LEGO Police Station: Toys & Games
Set #7288: Amazon.com: LEGO Mobile Police Unit 7288: Toys & Games
Set #7744: Amazon.com: LEGO City Police Headquarters: Toys & Games
Set #4440: Amazon.com: LEGO City Police Forest Station 4440: Toys & Games

In fact, the video attached to the link you provided doesn't even show set 7237. It actually shows sets 7288 and 7744.
