I'm partial to Canyon, but this isn't an option for them ATM. A new bar/stem is $400 and likely to be out of stock.
I also do not understand why bicycle manufacturers don't allow the rider to select the bar-stem at the time of order. When you force the rider to commit to such a rigid design that has zero adjustability they should provide some reasonable choices prior to purchase. As you correctly point out, these are not inexpensive parts to swap out.
I'm not sure if the trend with these integrated bar-stem combos will last. Yes, they are aero. Aesthetically, they are pleasing to the eye because of the clean, streamlined design. However, lack of adjustability and the added difficulty they create for basic maintenance may outweigh the benefits for many riders. The replacement of headset bearings is much more difficult, and many home mechanics don't have the skills or the patience to complete the task.
