Ask HN: Best cloud hosting service for Django

I had a related post on this a while back (http://news.ycombinator.com/item?id=1436719), but I have a Django app (http://www.trendero.com/home) that I'd like to move to a cloud hosting service. It's currently hosted with RackSpace, which is great but hundreds of dollars a month, and its traffic is such that I think it would be far cheaper (well under $100/month) on a cloud service.

I dig App Engine but am told that switching there would require a substantial rework of the Django models. I'm not a developer, so I'll need either (i) help (my offer of free legal work for help, http://news.ycombinator.com/item?id=1436719, still stands!) or (ii) another option.

Do you have a favorite cloud hosting service for Django apps? Any thoughts re: costs, switching, etc?

Thanks!
