SOAZ,
I'm really hooked on the 29erSS. Helplessly hooked. It's been a fun education as those bikes really are different. My humble advice would be to shop carefully for a bike with a short set of stays and extra stiff hoops. I'd also suggest hitting the core muscle routine asap as a SS really puts the whammy on your abs, back and even your elbows. I logged about 12 hours on my SS last week and my elbows were killing me from yanking on the bars.
I've got a good buddy up here in Prescott that is the guru for all things SS and 29er. He has a little shop off the town square. Cool dude. Has a Sportsmobile and a KTM 950. Very ExPo, if you know what I mean. I bet he'd help set you up with a sweet rig. He sells Surly, Spot, Soulcraft, Ventana, Yeti and a few others. Those new Spots are a crazy good deal at $1600 for a complete belt drive bike with hydro brakes, etc. Ed can usually build up something like a Surly Karate Monkey for around a grand. Everything he builds usually has hand built wheels, King headset, and so on. Nice stuff.
Come up and ride with us!
