Reply to Good deal or should i consider my options?

Hey guys,

so this guy has offered to sell me 2 cdj400s and a djm400 in a case for $1200. I believe its a pretty good deal. Currently i have my buddies setup comprised of a cdj400,gemini cdj600 and a behringer 4 channel mixer but he wants the stuff back so im looking to have my own setup.

My dilemma is whether its worth it to invest in the cdjs vs a controller with a laptop. I also currently have a mixtrack pro with my old laptop running traktor. I was contemplating getting an S4 and picking up a macbook pro 13in.

My skills with beat matching are average but nothing spectacular by any means. I really want to learn to be proficient with cdjs so i believe they are a wise purchase instead of picking up a new lapto/S4 combo.

What do you guys believe? Any opinions appreciated.
