LOT OF DIFF between them... beside the ratio I THINK CHEAP ONE ( GRANT ) IS NOT THE SAME DEEP THAN THE ORIGINAL and of course the accurate repro ( or at least was in that way on earlierrs products by Grant ). Beside that, the simulated seam all around on inner edge and spokes, is REALLY GREAT on the expensive one and unexistant on the cheap one.

I saw both at Carlisle and althought I was convinced on get the expensive one by the pics when I am ready, MY CHOICE was CONFIRMED once I looked at personally both.
