i don't think iv spent anywhere near that much on hop ups for ether my 10T or GT. racers maybe did. all iv ever done is replace what was broken or worn out. can't remember if the trucks came with bearings or not. pretty sure i put the MIP CVD's on them though. and i guess if installing RPM ball cups instead of OEM ball cups is a hop up, or replacing a broken shock tower with a graphite tower is a hop up then iv done more than im giving myself credit for. the shock tower for example wasn't done out of necessity, it was done because that's what my LHS had in stock, it was maybe $4 more but the guy behind the counter claimed it was stronger and i was a rambunctious 12 year old who liked to bash the BMX trails so why not. still don't think iv spent $250 though. although thinking about what iv said in this post $120 sounds reasonable.
im sure if i had this new T6.4 id do the same thing with it.
