Is there that much difference using the sear station vs. not using it. Both using direct heat on high with the lid closed ?

The sear station raises the temperature about 200 degrees sealing in the juices. I cook 2 minutes on each side and move off of the high temperature for 5 minutes on a side for medium rare delicious steak in 14 minutes. A much better flavor than without the sear station

What size female connector do I need to accept this grill's male gas line? Also, what size NG supply line do y'all have running to it?

You need a standard 1/2" natural gas line AND a quick connecter (NOT INCLUDED). This isn't obvious, so I hope the professional installer brings the right parts !! I have to hunt down the manual on the Weber web site, and it doesn't say what parts to buy. It only suggests you get a professional (? What, a plumber ?) to install the gas valve connector. This is very strange, because Weber is a premium brand and makes excellent grills. Weber shows the connector on pages 7-8. Look here for the manual (English and Spanish): https://weber.mizecx.com/retrieve/s3/knowledge/WEBER_LG/90925/90925.pdf?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Date=20200101T153248Z&X-Amz-SignedHeaders=host&X-Amz-Expires=3599&X-Amz-Credential=AKIAUA2JDF35TDNNDYWX%2F20200101%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Signature=fa25e9ee5bbe391b8fb21d19c14147590e8e078df9fd16b6a293125d6ef1fe66 I would post the diagrams, but there isn't any way to do it. I bought a 1/2" Natural Gas Quick Disconnector for $25 (Should have been included with the Grill) See: 1/2" QDD LP Gas Quick Connect/Disconnect Connector & Male Insert Plug [8630 3308] Solid Brass 1/2 PSIG Pressure Input 1/2 Ins & 1/2" Male NPT x 1/2 inch Natural Gas Propane Fitting Connector

dpes the grill ovme with a 10-year warranty like Home Depot offers?

Hello, this model does come with a full 10 year warranty on all components. The warranty is a manufacturers warranty, and is honored directly through Weber, not the retailer. Thanks.
