I got my HUGE Whirlpool microwave at a Goodwill. I think I paid $20. Had the glass rotating thing and all.
I used to have a lot of nice kitchen stuff prior to the whole "fall in love" thing. I managed to grab the industrial Bunn coffee maker, which I gave to my bud Rich. Jen trashed a lot of my knives and pans, but I could get new ones.
I picked up a Kitchenaid hand mixer for cheap to replace the big stand mixer that I no longer have. It works fine for my stuff. I got a stainless bartop Oster blender, that rocks if I want to drink something all blendy. I think that cost $5...
Aldi has decent pans. And I got a bunch of restaurant quality plates and silverware at a local thrift outfit.
I do need some better knives. I have found that Chicago Cutlery actually holds a better edge than some higher dollar blades.
