A little more information, here's how often I use my things.
Kitchen Aid Mixer KEEP Use every week about 2x's
Cuisinart Food Processor KEEP monthly
Hand Blender/aka Stick Blender KEEP weekly sometimes 2xs
Yogurt maker eh, if you use it a lot, I wouldn't 1 to 2xs a week
Vitamix Blender what on earth is that? Use the food processor? The Vitamix is a high power blender that can also crack grains for bread, will grind fruits & veggies into puree, etc. Daily
Rice Cooker a pan works just fine 2xs a week
Pasta Maker do you use it alot? Keep it if so! 2 to 3xs a month
Juicer if you use it a lot 1 to 2 xs a week
Toaster KEEP 2x a month at most
Waffle Maker KEEP 3x a month to weekly
Panini/Grill if you use it a lot weekly in winter 2xs a month in warm weatherCoffee Maker KEEP
Crock Pot KEEP 2x's a week
Electric Tea Kettle (our electric over takes 5 minutes longer to heat up) so? what's 5 minutes? More $ to the electric company, and in the AM every minute counts getting out the door . 4xs a day
Bread Maker KEEP 2x's a week
After the one suggestion, I think the toaster will go for sure. Crazy to think this but my food processor is looking like a close second.
I like hearing everyone's thoughts a kitchen is such a personal choice kind of thing.
I'd say your list is going to be different than anyone else's list depending upon your usage. For example, I would not want to be without my food processor -- I use it at least twice per day. (I used it five times today. Seriously. It's invaluable in my kitchen.) Yet you're not even using yours twice per month. So, for you, it would be reasonable to get rid of it. Get a manual grater and you'll be good for everything else with the Vitamix and stick blender.
It really is a personal choice as to what is useful to you. I have a dehydrator that doubles as a yogurt maker, because both of those things are useful to me on a regular basis. I have an icecream maker because it's one of they few ways I can get my special needs DS2 to eat a lot of fat and protien, to make quality, homemade, dairy-free icecream. So my situation is different than your situation.
If you're using an appliance on a regular basis, and you have room for it, keep it. Kitchen appliances are really amazing time savers, and time is more important to me than space.
