We got DD a JDBug one for her 3rd birthday (about 3.5 weeks ago), and she loooooves it! She has gotten pretty good in such a short time, and has started to pick both of her feet up a little and balances quite well for a little bit of time too, unless she has managed to pick up some speed. Only problem is that she doesn't really look where she is going, and so gets wobbly when she looks around, but she hasn't ever really fallen off yet... Most balance bikes are pretty hard to find IRL, and so have to shop online for them...the JDBug was cheapest on eBay for $95, up to about $135 in other places...

HOWEVER I found ours in Kmart - I read in a bike forum somewhere that people had seen them advertised in their catalogue for the toy sales last year, but never saw them in the shop. I was in Kmart anyway, and thought I'd just have a look to see if they had any, and they had one. There was no price anywhere on the shelves or box, so I took it to the price scanner thingy, and scanned it, and scanned it, and scanned it again, coz it was only $6! Biggest bargain of the century!
