Wife was looking out for a new fryer after foolishly trying to fry a steak in our old one (with only a teaspoon of oil - don't try this at home). This ultimately ruined the machine, so here we are.
This DeLonghi seems to fit the bill. It completely dismantles, meaning that all components can simply go into the dishwasher (minus the temperature control panel and timer which come off the body). The trouble with other cheaper fryers is that you have to tip out the oil but overturning the entire unit. Also, when compared to the other style fryers (the rectangular SS ones) you can also close the lid on this. On the others, the lid acts oly as a 'dust cover' meaning that oil sprays are likely and the fumes aren't filtered.
This is a great price when compared to other retailers:
