I bought a lightweight aluminium one last year Rosie and it cost me £30 plus 15ntl for altering the cotton mattress. Its a concertina action top to base ( so folds down to its footprint rather than foldup as the UK ones)and can also be used for a playpen. Shop is opposite the closest entrance to the fish market in Fethiye, lots of cots, chairs etc. outside on display.
