reverse bad beat - just how big of a longshot did I hit?

[DrewOnTilt]

I'm curious as to how big of a suckout I pulled on this hand.

I held 9 [img]/images/graemlins/heart.gif[/img]T [img]/images/graemlins/heart.gif[/img]
Flop was 8 [img]/images/graemlins/club.gif[/img]7 [img]/images/graemlins/heart.gif[/img]7 [img]/images/graemlins/spade.gif[/img]

The suckout victim held 8 [img]/images/graemlins/spade.gif[/img]8 [img]/images/graemlins/diamond.gif[/img] for a flopped eights full over sevens. I caught runner runner nines to win the pot with nines full [img]/images/graemlins/grin.gif[/img]

I figure that to win this pot, I had to catch one of the following:
runner runner 9s
runner runner 10s
runner runner 8 [img]/images/graemlins/heart.gif[/img]6 [img]/images/graemlins/heart.gif[/img]
runner runner 8 [img]/images/graemlins/heart.gif[/img]J [img]/images/graemlins/heart.gif[/img]

Did I miss anything on what I needed to catch? And the odds of this happening were what - one in 1500 or so?
