[Closed] Used 2013 Whyte 146, yay or nay?

I currently ride a 2011 Marin Mount Vision XM8 and really like it. I've been offered a deal on a slightly used Whyte 146s, which has a very similar geometry, only slightly longer and slacker and I love the looks of the frame. I've read reports of subpar build quality with the 2012 frames (hairline cracks and wonky rear ends), and was wondering if the newer ones (with the brace in the front triangle) are any better? I am only interested in knowing what owners think of the frames as I intend to build it up with my parts anyway, so don't care what the stock parts are like.

Any input would be appreciated.
