OT: Need to find a Rubber Made Dish Drainer.

[spacescape]

Ok, here's my problem... We want a square dish drainer by Rubber Made w/ a flexible / rubber bottom... We find lots of dish drainers (some by rubber made) but the drain mat (whatever they are called) are hard and non flexible. I can't find the flexible kind anywhere...

Anyone have any advice on WHERE to find these? I know they exist because my parents have the one we want.

Thanks!
Bill
