I got a baby cot from Baby Kingdom but if you buy during baby fair, they are much cheaper. Basically, most cots are almost the same, the more stylist they look, the more expensive they are. Then they have different mattresses also. I bought the combination mattress, 1 side is latex and the other side is coconut husk.
Baby cot's matteress height can be adjusted, so if you get those with 4 or 5 height adjustments, can use until they get quite big.
The thing about cradle is that they can only sleep until a certain age, then it is not safe for them to sleep w/o supervision. When the baby starts knowing how to flip, suddenly you can see them wriggling out of the cradle. It happened to my son in the afternoon and luckily I was just sitting beside him. My mom used the paperclip to clip the sides but when he was wriggling, his neck got caught in it so I removed that clip.
Cots can cost from $100+ (during baby fairs) to few thousand... Those at Mothercare are very very costly becasue the design is very very nice.
This company is so far, my own knowledge, the cheapest during baby fair, cos can bargain.

Not sure how much you can lower if you buy online. I went to their outlet to look at their cots before, but my husband's too lazy to return to their shop to order the cot after we arrived at Baby Kingdom, that's why I bought from Baby Kingdom.
