Not at all cheap, but the Babyzen Yoyo has just come out and it is AMAZING! I tested it recently. http://www.dorkadore.com/kids-babies/babyzen-yoyo-review/ Sorry, probably not much help since it's not cheap, but I reckon it will hold its value well on re-sale (which is how I will justify it to myself if I ever feel flush enough to buy one!)

I love bobux (they have some really good offers on their website) and Merlin Shoes in Crystal Palace do some lovely brands and often have them on sale (otherwise they can be around ?50 a pair).
