I don't know how close you are but there is a big swap meet in Pomona a handful of times a year and there are normally that kind of things there. Last one I went to there was a set of 4 17" 454 rims with a Ford bolt pattern for $550. I thought that was a steel but I didn't have the money to spend that time.
I've been looking for 454s for the last 2 months. I finally got word from one of the dealers, who told me edelbrock had ceased production and was hiring a chinese manufacturer to make the rims for them. Dealer told me that edelbrock said it would be sometime next year before they start shipping them again. Good luck.
Not sure if they are still being made but they are actually manufactured by Ultra Wheels: http://www.ultrawheel.com/wheel_detail.cfm?brand=4&id=14These were my first choice but I could not find them when I purchased my TTIIs.
I talked to a guy that carried them and he said he will have them at the beginning of the year but last time they sold 200 sets in a week they are that popular!
