After seeing these topics come up over the years I'm convinced that most folks in this category are better off building their own. I mean, if you need to house 500,000 products and have it scale, maybe you should make the investment and DIY?
Seriously. We've done our own and I'm glad that we did. It only has what the client needs and sure, it may be lacking in some of the really feature rich stuff but you know what? We've done just fine without it.
Most of the carts I've reviewed and demoed over the years fail at the basics. I'm working with one right now where the developers decided that it was best to generate table based deprecated markup for all the skins, just great! I've been through 50 of the 100+ templates so far and have removed tens of thousands bytes of deprecated code. Based on what I've seen, these Developers are using WYSIWYG and since I'm on Windows, I get all the Controls crap from ASP.NET, what a nightmare that produces.
I'm fortunate that I have a highly qualified dev on board. If I didn't, I'd be battling the same things you folks are. My suggestion is that you put out a call for a top notch dev. Give them a respectable budget to work with and build your own. Surely with 500k products, you can justify the development costs? ;)
