We're contemplating a scooter for DD's 3rd birthday. She can ride a balance bike quite well, and although she would love to ride her brother's 2 wheeled scooter, she just has a really tricky time doing so.

Hence why we were considering a 3 wheeler for her at this stage. I've seen 2 versions - 2 wheels at the front or 2 wheels at the back.

Apparently the ones with dual front wheels have a new turning action for balance, however I have only seen 2 models - the Mini Micro (at $119!!! - price of a bike!) or the Eurotrike Twist & Roll at about $50-$60
Or then there seem to be lots of options with 2 wheels at the back.

Anyone had experience with any of these brands or styles (can't find many reviews on the Eurotrike - lots on the Mini Micro)? Are the back dual wheel versions quite unstable?
