Oval cake tin

[LakeFlyPie]

I'm looking for a rounded oval baking tin but can only find ones with flat sides / bottom.
I want a half Easter egg shape.
Can anyone recommend one?
TIA

You can bake a cake in a pyrex casserole dish like this media.therange.co.uk/pws/client/images/catalogue/products/140020/large/140020.jpg.
I made the ladybird cake on my profile with one of these. It still needed a bit of carving once it was cool to make it more round, but it was a pretty good shape and better than buying an expensive tin.

Thanks TickledOnion, love your cakes

What I really want is one of <a class="break-all" href="http://www.google.co.uk/imgres?imgurl=d3w5aos35qel1w.cloudfront.net/img/2105-4793-main.jpg&imgrefurl=www.wilton.com/shapedpan/3-D-Egg-Pan-Set&h=269&w=269&sz=11&tbnid=rh7E3JGUrrZU4M:&tbnh=90&tbnw=90&zoom=1&usg=__N8TYrScfppzJH0j-fgna4IrpBnk=&docid=K6D8cF9W9fR8cM&sa=X&ei=wvKHUvXID-eV0QWNkoDICw&ved=0CFgQ9QEwAQ" rel="nofollow" target="_blank">these and I think my Mum may have one but she's on holiday

I was wondering about using a round pyrex bowl which worked well for a volcano cake I made before but I need more of an oval (Octonaut Gup A!) so the casserole you suggest may be better.
