Purchased the Signet 320 a couple of weeks ago and so far very pleased with the Bbq. We bbq every Friday and I am very particular with performance.  The bbq seems very sturdy and durable and should last me much longer than the Nex Grill that rusted through. Truck is to make sure you cure cast iron grill racks first and before each use, and also to give bbq time to preheat.
