Honestly, for me it depends hugely on shipping rates, since they're heavy and I don't really know the cheapest way to ship something like that. Ultimately, I wouldn't want to spend more than about $80 total on the sub-frames. If shipping is expensive, it may drive down the amount of money you earn off the deal to the point of it making more sense for you to sell them locally (and me to buy them locally).
Regardless, for reference, I see the sub-frames occasionally listed locally in the $30-40 range.
