Turners are great bikes. I personally would get a flux over the nitrous.
As for the horst vs faux bar. I believe that is an over hyped comparison. The wheel path of a tnt turner vs a horst turner has 1mm difference. I had a well executed horst design (titus) and I have a tnt turner and I tell you the difference in suspension performance is minimal. If anything I give a slight nod to the Turner. It has been discussed ad nauseum on mtbr and other forums if you care to look.
Bushing vs bearings is another non starter. They both work fine. I like my bushings better because I can grease them and I personally believe that they are more suited to this application. That fact however would never keep me from buying a bike with suspension bearings.
Turner and Ventana make great frames. Both are worth having if you have the scratch. I think you can get better deals with some of the other companies but you don't get the feeling of superiority that comes with a boutique frame
I lusted after an el saltamontes before I decided to go 29er. I was going to go GF to save money before I stumbled across my turner for a steal.
One thing that people might bag on the turners for is DT penchant for using shorter stroke shocks. My sultan has a 1.5" travel shock on a 4" bike (most use 2" travel). This was a major concern of mine before I rode the bike. DT feels that fox shocks perform better at a 2.5:1 ratio than they do at 2:1 ratio. Not being a suspension expert I cannot argue with him. I will say that mine performs flawlessly and does not have that midrange "wallow" I used to get on my titus when it was in 4" mode.
If you are really sure you want the 3" I would look at the el fuego and the racer x in addition to the nitrous. If you decide on a racerx let me know and I will point you to a good seller.
