Reply to Buying more equiptment.. What to do???

So I recently made a few extra bucks at work, so I'd like to buy some new stuff.. I currently have a pioneer ddj-sx.. I love it, but would also love a pair of pioneer cdj's as well..

I've been searching around and have seen some pretty sweet deals on craigslist.

One option is finding a pair of used cdj 2000's for around $2000. believe it or not I have seen them at this price a few times, but you have to time it just right. They move fast..

Another option is a pair of cdj 900's with a djm 700. I found a guy selling that set up in good condition for $2000. Also comes with flight case.

Basically I would like to spend around $2000 for some new gear. Something that will last long and hold some value.

What do you believe?
