I found a local shop that *REALLY* seems on top of their game. They sell primarily 29er's and high end-ish road bikes. The owner seemed to know EXACTLY what I wanted (Open Pro + Ultegra), quoted a price on the spot, and promised it would hold me and stay true.
He wanted ~$200 to build it for me, vs ~$120 from Performance Bike. Is it really worth the difference (I am all for supporting local shops, but in this case I am a bit short on money lately, and biking is sucking everything i've got. If I can save $80 I'd love to).
