Stunt scooter for 6 yr old DS

[topsi]

I am thinking of upgrading DS scooter for Xmas. He has a 3 wheeler at the moment but was watching the older kids at the skate park the other day. Has anyone got any recommendations please? Was looking at the Micro scooters? Some brands are way too expensive, am looking at around the £100 mark.
TIA

DS3 has a JD bug which we bought second hand for £30 then we just replaced a couple of bits to spruce it up a bit. Total cost: less than £50.
