I just payed more (almost double) for a NIB 5.5 Bull, Stainless, and I dont regret a dime of the price. As they said, they are out of production, so just decide what you want and how much it is worth to you.
This was, quite frankly, the only gun I was thinking of, so from my perspective it was a steal even if the "market" value is lower.
I did not buy it as an investment or to sell it.
I bought it to shoot it.
Best of luck!
