If you're going to tune your bike regularly from a pro, consider buying it at a shop like Sportinglife where they include 3 yrs of tuning with the purchase price. If done once a year, that is worth about $150 to $240. So for a total cost of ownership of about $750, you can also consider getting a bike from a more specialized store.
I had originally picked up the X29 but returned it and ended up at Sportinglife.
