Jolteon* is somewhere around 15-20
Wailord Ex is currently on ebay for auctions going for around 30-40, but if you put it up for a BIN of 60, it will sell, so I would go with about 60 for it.
I can't give a price for the IFDS Lv. X but a average of about 18 ea for them sounds reasonable based on what I have seen.
