I've had the basic XC7000 frame (don't think it's the triple butted one) from CRC (Brand X – same frame, without the somewhat intersting stickers) and it's superb. There are loads of positive reviews on CRC for them as well. Wife has the shorter jump bike for her regular bike and that's a nice frame too. They appear to have some quite nice looking paint finishes now at CRC – the blue looks good. Sure, it's no boutique make, but it really does cut the mustard for the money.
Mine was set up singlespeed with a tensioner, and it's now in the process of being winter-biked with some rigid forks, mudguards, 3×9 gears and slicks from the parts bin at home.
I don't think you'd go far wrong with it.
