Pretty much curious how much everybody else has spent on something in one go thats considered 'nerdy' not talking about a gaming rig pc or games console though, those are fairly standard.
I play a trading card game called yugioh, and have spent some silly money on that but made a lot too so its counter balanced. However I just brought a Lightsaber replica for arond £340 which i'm recouping a chunk of the costs from the cards I have spare and are valuable aside from looking cool as hell, and being a childhood dream and using it at a comic con it has no use but to look cool.
Whats your biggest nerd buy?
