Only thing that can be REMOTELY worth it is something like the Ham Shank,The Objector or the Freedom Staff. But that stuff can still just be crafted anyways.
ham shank is $2.49 in the store and only worth a ref
objector is $12.99 in the store and only worth 1-1.33 ref
freedom staff is $4.99 in the store and only worth 2 rec-1 ref
it isn't even close to being REMOTELY worth it at all
