This is universally true, no shame in that.
As you grow into the hobby, you can start saving money until the budget grows into it.
Some people also build their own, choosing to save a lot of money in exchange for time, sweat, blood, and tears. Line sets cost about half as much but require buying in bulk up front; yards of kite fabric cost have some waste as you cut around, but then you've got people like @riffclown who make impressive patchwork kites from hundreds of tiny scraps of fabric.
Assuming you stick with the sport, you'll have one, then another, then another, then you'll talk about your collection with pride, then you'll talk about it with embarrassment as you forget how many total kites you own. (I'm at 24, but Christmas is coming, plus I've saved up for the Djindoor when it is released...)
