Earlier quoted context omitted.
$1500 is a lot for an oven that can't cook very much food. It looks like it would serve two people, max? And it can only cook one thing at a time so wave goodbye to roasting veggies while the meat cooks. People who are passionate about cooking tend to do it for more people than just themselves.
It fits a 12 pound turkey. That's a small turkey, but it'll feed a lot more than 2 people.
And, for those who find a turkey a less-than-stellar example for whatever reason, a 12-pound turkey is a lot larger than a roughly four-pound roast, which (with various different marinades and preparation techiques) is the base for lots of ~6-8 serving main course recipes.
