Who sells round chopping bowls?
I've had round large round chopping bowls for years, that I use with a rounded chopping blade - I think it's called a mezzaluna.
It's time to buy a new bowl and I can't find them anywhere, for anything near a normal price. The absolute cheapest are about $38 on Amazon, and I'm not even sure this 12 inch size would be large enough.
I also had a large plastic/acrylic one (same material as they use for flat chopping boards) which went MIA during my kitchen renovation. I'm sure I didn't pay much for it.
I guess I'll have to cough up the money, but it seems a little outrageous. This was an item that was available all over, and was not expensive.

I don't know any bowl (on sale) which is designed for a mezzaluna, but I know there are cutting boards designed for it. However, if you want cheap ones, you aren't likely to find one.
Anywhere. You can look for this kind of cutting boards:
I'd flinch at paying that much, too, but those chopping bowls are expensive because they have to be so thick in order to not crack when you chop in them, and because they're usually turned by hand from one big hunk of wood. The wood alone is $25 or $30 if you buy it at a retail carpentry-type place, so I think $38's a pretty good price. You could probably find a thick vintage teak bowl from the 70's on eBay or at a thrift store for less, though. There are also older wooden "dough bowls" I see around from time to time that might work. I know this one isn't big enough or curved quite the right way for your purposes, but maybe something like it?: http://www.ebay.com/itm/VINTAGE-DOLPH...

You just have to make sure no one's polyurethaned it to use it just for display.
