Smallest possible
Although the C34 is a nice roomy boat, you don't have room to waste. Most likely you'll be using your microwave for what everyone else uses theirs for: popcorn, heating water/coffee & reheating small portions of food. I'd take measurements of several different areas (cabinets, counterspace, etc) and then go to your local appliance store & find one that fits the size AND wattage capacity you want. I'm an electrical dummy so can't help ya there!LaDonna
