Thats a good looking rack, but always consider the saftey factor if you get into a crash. Those edges could result in the loss of a limb, particularly on the very end of the machine because you will get the full weight and momentum of the machine.
This was a reason they put balls on the levers.
Just something to think about, but if the price was lower, I would prolly forget about the edge, yea for 30 I would forget about it!
