Under the cabinet microwave

[Maddog]

It is not really going to work for any effective venting, but is likely to work well anyway. I tend to like the Sharp models myself. I would make sure you are getting a least 1000W and have the instant add feature (you know, press a button and get an extra 30 seconds or be able to hit the 1 for 1 minute, etc.) If you don't have this you will not like it. Your local appliance store will often have these in the scratch and dent section, often from home show displays. You can pick up a good deal there.
