I found some on ebay, but they're all in the UK with a $40-50 shipping charge. Anyone know where I can buy one in the US for a fair price? I want one that's adjustable so I can use it on any future bikes and even with the coilovers in my car.

 

I bought an adjustable spanner from my local honda dealer for $17.50. Wasn't the greatest quality and the "arm" was short, but it got the job done.
