Where do you find a clothes airer?

I remember when I moved to London, the big issue was where did I find a hairdryer? I am now savvy to these sorts of requirements (look for a chemist - have already bought my NY hairdryer and straighteners - why did noone remind me about the humidity - I am a furball here with the frizzy hair!), but a clothes airer - that is harder. I am about to discover the laundry room in my building. I have already done a quick reconaissance, seeing the machines, what sort of stuff they take, checking out the cost on the card operation mechanism... So now I am almost ready to take the plunge! However I refuse to put my "unmentionables" through industrial washers, and equally do not want my jumpers and shirts to be heat dried (and shrunk), so I thought I must get a clothes airer. But where to go in NYC for that? I don't think my shoe frenzy of shopping yesterday in Saks helped to solve this problem. I sense a mission ahead ...
