I've got one, but I intend to use it as a playpen/toy storage box more than a travel cot really. Ours was 25 quid from asda, I think 50 is very steep!
Drives you mad people trying to sell you stuff doesn't it, lol... Its kind of people but all these items really add up when you're not sure if you want or need them! I always find it awkward to say no, so I've started saying 'oh thanks so much but I think the baby's other nanna/auntie/friend is already buying/lending/giving us one of those!' x
