Big Block M code Exhaust Manifolds

Great looking manifolds and I need one more set for our other M code and I know how exceedingly hard to find these are as we have one set, but in this "new" market with everything coming back to real #'s on the cars I just can't get myself to part with $4K for another set as it is so hard to justify it nowdays with soft prices. $2500 I would say is about the comfort level most guys would have on these for a resto nowdays and I would jump at any complete nice set for that price level but $4K makes the accurate ltd pieces or headers a more cost effective route and I do not know if you can get the extra money out of an M code nowdays to offset the extra cost. Just my thoughts and I may be way off.
