yeah to be fair, before i got 1210s i went through:
1x set of shit citronic belt drives
1x set of vestax pdt-5000
1x set of vestax pdx-2000
1x set of vestax pdt-5000 (again)
1x pdx-2000 and 1x other vestax deck, the weird battle-style one
and about 20 mixers.
now settled on 1210s + old xone:32, which is what i wanted when i fkn started djing to begin with
just saying, if i could do it again, i'd have sucked it up, saved pennies and gone straight for 1210s. i started djing with the intention of playing out and practiced mixing a lot before my first proper gigs, but being accustomed to vestax pdx-2000s (which are fucking great decks) did not help when adjusting to 1210s on the fly in front of a crowd.
it's like the opposite of going from belt drives to directs - you're only just getting used to the torque and pitch at the end of your 60 min set. it's not a good look.
after enough gigs you will adjust to 1210s regardless of what you have at home, but if you're not lucky enough to get a residency based on your selection (like i did, jah bless) rather than your mastery of the equipment then you're gonna embarrass yourself in front of people quite a lot.
plus they're built like a brick shithouse and hold their resale value.
