The one I purchased is found here:
It is currently listing for $450 but it appears they have broken out what use to be in the kit and now you have to also get marquee retainers, and t-molding for an extra $20. But one thing nice is thy are selling the clear plastic marquee which I had to go to a local hardware store and get cut to spec. So looks like things are a little easier but a little more expensive.

I had to pay around $120 for shipping so that would bring it to $600. I suppose the ebay option if it is delivered and new condition is not bad option.
