Let's talk Backing plates!

So My original backing plate has finally bitten the dust and I`m looking to get the 5" in addition to the 6" that came with the machine. My question is this! Are there any other options I should be looking at? I`ve heard of the Kamikaze BUT not sure I`m ready to pay $100 fro a backing plate. I`m also looking see if there`s another option aside from the Rupes or Kamikaze. Some of the knock offs (like the torq one) has a very similiar looking pad and it`s like $20 something instead of $40 something. Just looking for options!
