Cold food

So I went to eat my dinner cooked in the oven tonight, my stomach had not seen food since 11am and it was 6.30pm, it was cold must have forgot to switch the oven on silly me, no such luck dam oven has stopped working.
So now what to do, get it repaired the electric cooker and oven is very old, purchased when I had no ready cash having just having put down a deposit and got a mortgage.
Not only that is was a second so I could do with a update come to that, saying that so could the kitchen.

So repair or new? also gas or electric? all the fittings are there or perhaps make do without and buy more kit.

PS don't worry I blasted my food with microwaves so did not eat cold food.
