Tosh,
I'm with Joe on this. I bought the Duralevers and did not like the way they looked and opted for the real deal from SLS. The illumination of the plastic levers is, in my opinion, one of the real distinguishing features of the dash and well worth the extra couple of hours to take the dash apart to replace. Make sure to get new bulbs before you start the job. If you go slow it is still "only" a 4 hour job and on your first night drive you will bask "in the glow of the dashboard lights..."
