For the money, I would take that 850sci 39 with 6's all day over a new 700/nxt boat. It's not worth it if they were both new because the 850 boat would be dramatically different in price. Those 850's will last 200 hours, maybe more. The 6's hook up so well and the 850's speak for themselves. When the economy recovers, and it will, that boat will be worth likely as much as you pay now when someone prices a new one set up the same.
I've ridden an 850sci 39 w/ 6's and a 700/NXT, so that's my first hand opinion. If both were new, no question I'd take the 700/NXT boat. I'd definitely take the 850 boat for those numbers though. Just my completely worthless thoughts. I'm wide awake and bored. :ack2:
This is the one I rode:
