I got the cheap $5 set. It is nasty and the pegs seem to be pointing in the opposite direction of the ones in the tutorials lol, but we are only doing simple ones. I am not overly good at it - other day I did some that looked right but when I went to take them off it seemed that none of the bands were joined to each other and the whole lot shot off everywhere. I managed to do that three times in a row! Tonights effort was a bit better and all three kids went to bed happy with a new band

I guess if you think you will get a fair bit of use out of it then the brand ones would be better but if they are only a causal novelty thing like ours then el cheapo works just fine.
