I recently browsed the Kelby Training website. I hadn't been interested in the past because I thought it was just PhotoShop training. There are some great courses - including food photography that look interesting. Cost is reasonable - you can access all the classes per month or per year. You can test drive the courses without having to sign up for anything - a big plus. And the video plays great!
