Reply to CDJ-800 (MkI or II) or Numark NDX 800

I'm finally ready to take the plunge and pickup CDJ's. I have been researching and gathering people's recommendations and have come down to these two for the money I want to spend. Currently I can pick up a pair of brand new Numark NDX800 for about 800$ or a used pair of Pioneer CDJ 800 (MKI or MKII) for about the same price.

Given this option which would you take?
I love pioneer. I loved my Numark Total Control though. I haven't heard the best track record with their previous CDJ's but everyone has something positive about this model. Any additional feedback before my wife notices I spent another grand on my "stupid hobby"
