I carry my bass around Edinburgh a lot (Edinburgh bassists: if you see a skinny guy lugging bass across the meadows and looking thoroughly exhausted, it's probably me!), so a wheel seems like a good idea, but I'm struggling to find one without ordering one from the states. Does anyone know where to find one? Are there any UK stockists of the gaines wheel for instance? The contrabass shoppe stock does one, but it seems a little small compared to the Gaines or other wheels, and it's not cheap at £76. Any hints (other than getting a car....)?
