Reply to Gemini CDJ 700 vs. Pioneer CDJ 850

I'm getting pretty close to finally just making the jump to CDJ's but I want to be sure I'm making an informed decision before I purchase. That being said I've probably narrowed it down to either the Gemini CDJ-700's or the Pioneer CDJ 850 but I'm not really sure which one to get. I'm sort of biased towards Pioneer because I feel like it's more brand name and I've heard the build quality is a little better but I'm not sure I really want to pay for the hefty price boost associated with it. Does anyone here have experience with one or both of the two that can tell me their thoughts on the differences/similarities between the two? Thanks a ton!
