Moved in about a year ago and appliances were all left by seller so can't really moan but am very skint just now and it looks like I'll need to get a new one 
It's a built in fan type single oven with a grill and last night was not heating up properly - a bit of heat but not enough to cook anything. Any advice on cheap good value integrated ovens please? Also this one is plugged in rather than wired in? Is this common - hope so as don't want to have to fork out more money for an electrician.
Will I be able to lift the old one out and fit the new one myself - from reading it seems they're pretty easy to unscrew and put in, has anyone done it? How heavy are they - I'll have to do this myself - am pretty strong but don't want to strain anything! Sorry, lots of questions but any advice appreciated - don't need anything fancy, just basic oven and grill
