I have been throwing for about 5 years and have spent about $1000. That is cheep compared to most hobbies.
I only got into throwing in February-ish and have spent probably 200 give or take some plus string and lube.
I’m around 3 or 4 weeks deep and am around $250. Having said that, I think my spending spree has come to a halt. Unless… I see some shiny stuff at the Cleveland Juggling/yoyo thing that is happening next weekend.
Bought a few yoyos, quite a few different strings to try, thick/thin lube, couple different bearings to play around with…
maybe around 600 give or take some.
Yay! The title was fixed!
First, thanks for fixing the title. ;D
Now to answer the question, thousands and thousands less than I spent on RC FPV.
I dont think it matters as long as your content! As long as you keep buying and keep loving it should never matter!
According to my wife…I’ve spent $700.00…since August 2015? Spent most of it on the YYE website…
But…then, again…I don’t keep track…of what or how much…my bad! 
A happy wife…means happy life! Don’t forget that guys!
A little over $3200, not including the ones from the 80’s and 90’s I bought.
I just went through a decade of emails. From 2005-2015, I have spent exactly $549.76 on online yoyo purchases.
Enough to have backpacked Asia
Just under 300
Oh my… Lemme add these up hold on. About $1550 :o
Started a year ago and so far I’m at about $350ish
My wife added up said something like 500ish ?? But some have been great deals on used ones on ebay. ; )
Over 9000!?!!?! Almost quite literally :-X :-\
