Good question! I found an NG platinum series on Craig’s list for $50, restored it, and gave my LP restored Platinum Genesis to my mother in law who was in desperate need of a new grill. So, that resolved all my grilling needs.
I’ve subsequently been on the lookout for a backup NG manifold on the local Craig’s list, in case the manifold eventually fails on the NG platinum I picked up (I rebuilt/cleaned that manifold’s valves but the manifold tube has a decent amount of rust). I was driving home yesterday and saw this bad boy for free on the curb (an NG red head 1100 Genesis). I’ve always wanted a red head, so am going to restore it, keep it (along with the backup manifold), and convert my Platinum back to LP and give it to my brother in law (who is also in need of a grill and loves the look of mine). The only thing stopping me from giving him a complete LP grill is the propane holder, which again is now with my mother in law.
Probably a much longer answer than you bargained for, but there ya go.
