Hi,
I had been eyeing the Weber Genesis but was reluctant to pull the trigger as I did not like the control valves taking up shelf space and I wasn't crazy to spend $650. The Ducane 4100 Affinity was the closest grill I could find to come close to the Weber in terms of quality and cooking prowess based on reviews from several sites that have been very positive. I really wanted to see it before I bought it online but no one in my area had one on display.
I ordered it from Amazon and received the grill in 2 days with the Prime membership, assembled it Saturday and used it Saturday and Sunday nights.
What I like:
Assembly was fairly simple. This is a heavy grill. I assembled it myself but could have used a helper to lift the grill top onto the frame (as the manual suggests :) )
Fast Heating - as others have said the grill gets hot very fast. 10 minutes with all burners on high with the lid closed and it is at 600 degrees.
Even heating - as others have said the burners are good quality and heat is evenly dispersed.
Parts fit together nicely. Nicely engineered and machined. Gas hose is away from the heat (as much as it can be while under the grill) and has plenty of length.
The shelves and control panel are made from some material that is very easy to clean. At first I thought it looked a bit cheap (my last grill was stainless) but I have to say this cleans up in a snap.
Ignitor for each burner. I like this a lot - each burner can be lit separately and quickly.
Porcelain burner covers. Steep angle tenting over the burners - nice design.
Cooking space: Had plenty of room for 4 large steaks, 1 lb of asparagus and red potatoes on 4 skewers. 2 burners were on high and 2 on medium so I could move stuff around.
What I don't like:
Stainless steel cooking grates (although I prefer the two to one large one.) The grill was advertised with a porcelain enamel cooking grate but came with a stainless one much to my dismay. The stainless has already discolored, which I knew would happen. Amazon has told me they will adjust the description on their site.
Warming rack. Ironically the warming rack is porcelain BUT, it sits on a couple of thin pieces of metal protruding from the sides of the grill and is not attached to anything. Since I use a lot of the grill space I was hitting it and moving it up and almost off its seating. It does have 2 holes on each end so I ended up using a screw, nut and large washer to attach it to the metal seats - this solved the problem with it moving. Maybe others don't care about this but I don't like the unfastened warming rack design at all.
Cheaper grade of metal. As others have said the quality of the hood and doors is not the same as the Weber, (after all it is $120 less) but it is not so thin that one would call it cheap.
With all things considered so far I am happy with the grill. I looked at all of the options from Lowes, Home Depot and Ace Hardware. If you have the $$$ I'd say consider the Weber (if he %#@$ placement of the control knobs doesn't bother you.) However if you want good quality and a little cheaper price, consider the Ducane.
