The main thing that decides whether you buy CDs or vinyl is you budget, years ago I bought a pair of turntables and have stuck with them... only problem is records are so expensive and you need to collect alot before you can start doing any decent work, I've spent thousands over the last few years on my record collection.
However with CDs or turntables and a digital vinyl system, you can play MP3s which can be bought for a couple of quid now off beatport and dnb arena.
The things to think about are do you have a decent record shop nearby? and do you have the cash to be paying between 5 and 8 quid a record.
