My wife has a Scale 910 and we got her an 041 as a backup. Although the geometry is a direct copy of the Scale, don't expect it to feel the same. She found the Chiner version to ride harsher, but not accelerate as well. I attribute that to carbon layup, Scott frames are designed with specific carbon orientation to optimize frame stiffness/flexibility, whereas Chiner frames throw carbon in a mold until you've got a frame. That's part of what you get with all that extra cost. (or what you give up to get those savings) None of the Chinese frames are "the same as" a Scott Scale, I can promise you that.
That said, the 057, 256, and 041 are direct copies of the Scale geometry, with only small discrepancies here and there. Out of those, the 057 is probably your best bet, as you'll find a bunch of instances of the 256 having cracking at the rear seat unistay, and my wife's 041 cracked in short order because of a defect in early frames. I know several folks (one of whom is on this board) that have the 057 and have beaten them with zero problems, so if you want a bike with a copy of the Scale geometry, the 057 is your best bet - and is also the least expensive of all those.
