Collector's Pro KS Gunslinter mini suggestion

All recent sales on the SCM(Keys = $2.49): http://steamcommunity.com/market/listings/440/Collector's%20Professional%20Killstreak%20Gunslinger

$39.99

$52.38

$56.31

$38.00

The average comes out at $46.67(Roughlyv 18.5 Keys)

Only useable sale I could find, 20 Keys should be fine.
