Ordered and installed OEM coil. Will-fit products are available in the aftermarket for significantly less up-front cost, but the OE coil lasted 18 years and I wanted that reliability in the replacement. AppliancePartsPros.com had a video on the replacement procedure which figured heavily in my decision to buy from them. Finding and ordering the right part, packaging, tracking, delivery time...everything about this transaction was exceptional. The next time I need an appliance part, I'll be back.
