Wanted - drying racks for onions etc

[Sue]

Having just missed getting some via the forum recently, I wondered if anybody else had any - or anything which could potentially be used as drying racks for vegetables such as onions?

Preferably stackable and preferably with a reasonably large drying area.

I have been improvising with those racks you put cakes on when they come out the oven, but they are far from suitable :)
