I had my center wood piece refinished by Madera Concepts in California. A decent used piece without cracks is likely to cost you in the range of $250 with minor defects. They can refinish to factory new condition for less $. https://www.maderaconcepts.com/NewSite/ ... s_benz.htm
Here are pics of mine. It was cracked, chipped and opacified, basically in rough shape before I sent it down. I had them mill an additional hole for a second child safety switch as well.
It was refinished in 2013 and still looks like new.
