There is someone up in York PA that keeps a bunch of Oscars, you might be able to get in contact with them through the Cichlid Club of York on Facebook.
CCY or monster fish keepers.
As for price might end up being next to free. The p. crabro are pretty but they are super aggressive so that might be difficult too.
Try lfs I believe the one in pg county has a few monsters, so he might be willing to trade with you for food equipment etc...
