My old Baumatic cooker has been a pain in the arse since I overpaid for it around 6 years ago. It's always made rubbish cakes for example and also puts the most useful burners at the back for safety reasons. 
It has finally died so I can justify getting another.
I need a four ring cooker. I want it to be good because I do loads of cooking all the time. My budget is around £500.
I'd appreciate any help as I don't want to make the mistake of buying and having to put up with a crap cooker again.
