Get an ultrasonic LP cleaner for sure. Even when I clean new records, there is a bunch of vinly chips and dirt at the bottom of the bath when I clean them ultrasonically.
Especially you will need one if you expect to buy any used LPs (which has sometimes worked out great for me, sometimes not).
I don't use a mutl-thousand $$ unit. I use a generic ultrasonic cleaner and an included LP mount that rotates the LPs through the claning bath. Chinese units for about $250 incluiding everything. Works great!
I still cannot believe how quiet the LPs play now. I would say eliminates 99% of snap/crackle/pop.
