In the years since I first learned to to cook, I have never owned anything that was over $100 that could make my cooking better. This is part due to not having the money to buy anything nice and part due to stubborn resistance. If I never had a Le Creuset then stews basically tasted as I expected them to, and if I always kneaded dough by hand, I could never know the ease of having a Cuisinart dough hook.
On the list of reasonable Thanksgiving appetizers, a bucket full of donuts would seem to rank right down there with a full pre-meal turkey or a Domino's pizza. Anything heavier that crudités and a plate of cheese and crackers, and your guests will surely end up pushing around their mashed potatoes listlessly, barely nibbling at the turkey you spent hours trussing. The sane thing is to give them a glass of wine and a few mini-quiches.
