I have 1200’s and a nice Vestax mixer but hardly use them these days, stopped buying vinyl about 10 years ago.
I use Mac with Traktor, organise files in iTunes which then you can see in Traktor, makes for pretty streamlined workflow. Have two controllers (X1 and Z1 from Traktor) which are inexpensive really. Played a mates house party last night and took the lot in a laptop bag. You don’t need an audio interface although I do have a cheap Behringer one. It’s a vaguely ‘toy’ like solution but Traktor is pretty bombproof these days.
It’s ideal if your just making ‘tapes’ at home and the odd party, but if you are playing out with any regularity Pioneers are the way to go. Maybe one day but just can’t justify the £££.
