well i did see just toy fridges on ebay as well, they were generally plain wood, you could paint it to match.
its a shame its only available in pink, but its not a hideous pink, the only difference i coudl see between the pink one and our blue one other than the colour was our cooker had a drawer under the oven on the right hand side, whereas on the pink one its an open shelf? the handles, cooker top, sink etc are all the same.
you have no idea how long i spent googling and looking at toy cookers when we decided to get one!
btw there is a make called melissa and doug that do wooden play food, we have these www.ebay.co.uk/itm/Melissa-and-Doug-Bake-and-Decorate-Cup-Cakes-Play-Food-Brand-New-/190645523395?pt=UK_Toys_Creative_Educational_RL&hash=item2c635bd3c3
which are toy cupcakes and they come with special 'icing pens' and you can colour in and decorate the icing! my boys LOVE them, they also do some cookies with various toppings that velcro on and LOADS of other stuff! just type melissa and doug food, into the search bit on ebay, in the toys section andyou will find loads, they do other wooden toys as well, not just play food, but their play food is AWESOME!!
