I don't know about ceramic plug-in heaters, but I did buy a heated clothes airer last year. It was pretty cheap as it had already gone out on mail order and been sent back, so brand new and undamaged, but the box had been opened and some packaging replaced.
It is pretty good at being a clothes airer, much cheaper to run than a tumble dryer and also heats a room. If I put it on downstairs in the dining room, the heat spreads around into the living room and kitchen.
