Thats an excellent price. I just bought one several months back from buds and it was $469, which was a great deal too. Then PSA had them on sale for $449. Looks like you grabbed it, great choice as its an awesome pistol.
And yea, I have seen places selling them for around $600. The cheapest price I could find them at my LGSs was $589 and several were well over $600.
