Delonghi stove repair

I am ready to throw my oven out the window. It is an electric stove with a gas hob top - freestanding, about 9 years old. the front rh burner only starts if I hold a naked flame to it, which I guess isn't too much bother, but the oven!! OMG - I've had a gutsful of it. It randomly turns itself off, then I have to whack the front of it with a meat tenderiser to get the damned thing to start again. This happens constantly. I have absolutely no chance of been a master chef with this oven! Add to this the knob on the front left is broken (due to meat cleaver smashing) and I'm ready to burn it to the ground. I'm looking for an estimated cost to repair - top end price please, because I dont know whether its even worth fixing.
