Most people do this as part of a club. You join the club and combine everyone's money to buy the things needed, and then everyone in the club can enjoy it.

"Clubs" as a thing is such a great concept, and if you feel like there is some humanity missing because of all the things going on, they're real places with lots of humans and humanity in them. They work great for lots of things, from trains, computing, music to boats, puppets, gardening and whatever else. If there is no club where you live, you'll surely find at least one other member if you start it yourself :)
