i've got a madd gear pro team edition, got it second hand off the bay. 
 
it's pretty tough, i got it mainly cos it's tested up to 16 stone! 
 
slamm scooters look pretty good for the money, quite a few of them locally, or jd bugs can be had cheaply second hand. 
 
if you wait till after xmas all the spoilt rich kids'll have their old ones on ebay!
