Would you buy a used carbon bike that has been repaired?

I'm searching all the usual places for a carbon canti CX bike for a reasonable price and I'm largely striking out. Last night I found a few Ridley X-Night bikes being sold by Pros Closet that are in my price range and I was ready to pull the trigger until I noticed a disclaimer that noted the drive-side chain stay had been repaired by Broken Carbon but came with a 5-year limited warranty. I emailed PC about the repair and they informed me that they don't have any more info about what the damage was or how extensive the repair was. The eBay sale post is here if anyone is interested. I can't make out any real damage from the photo of the chain stay other than some obvious chips that look like they were painted over.

My question is this: should I drop $800 for a frame set that was possibly too damaged to ride? Should I be even considering a bike that was beat on for a few seasons by a pro team?
