I've also seen Silvers that size around my neighborhood for about $35-50ish. Haven't seen any black arrows in a while though.
The cheapest jardini i've seen so far is a 2-3" for $30.
On a random note - I was on my way home from a road trip and dropped by a random lfs I happend to be passing. They were selling a green arrow, 4-5" for $600. Seemed kinda steep. Don't think it was certif. either. haha I wish i had that kinda money. I'd buy a tank with it!
