$530.00 would not scare me away if I was looking for one like the one you are considering.
When I epoxy bed a 99 buttstock, I try to direct most, if not all, of the recoil forces at the wood directly behind the bottom tang.
The wood behind the top tang and the wood that comprise the stock cheeks is thin by unfortunate design so is evidently prone to crack. I try to leave hairline gaps where the metal meets the wood at those interfaces.
