Ease of cleaning is well worth considering at the outset. Stay clean liners resist dirt build-up but pyrolitic cleaning is the ultimate. It burns off all baked-on debris at 500°C so that all you have to do is sweep out the resulting ash. Look out for ovens with a steam cleaning facility, too, and remember that some ovens have removable inner doors that are easy to clean.

This is a big ticket item, but worth its weight in gold. It will save so much time when it comes to simple chopping or more advanced preparations like mayonnaise. As with most things, buy quality-- it will last longer, be capable of tougher jobs, and give you less problems. To make the food processor easiest to use, leave it on the counter top instead of storing it in a cabinet.
