I bought a new grill last year and it was between a Weber and a Ducane. Similar models, though I don't remember right now what they were. I bought the Ducane. Reasons being, 1-It seemed like I was getting a lot more grill for the money (they are made by Weber BTW), 2-I liked the stainless steel grill racks. They were what I was used to and I didn't need to worry about protecting their coating/finish or seasoning, 3-The burners went front to back rather than left to right. This meant I could run the outside burners and have a nice area in the middle for indirect cooking. (For that reason you may want to consider more than a 2-burner grill.)
Unfortunately, you picked the wrong time of year to shop for bargains when it comes to a grill. I got mine for cheap at a local hardware store last fall, but that doesn't help you right now (but for next time
I have used my grill at least 2x a week since getting it and for a stretch there, probably 8x a week, as I was cooking dogs or burgers on it for lunch, too. I am very
happy with it.
Just giving you more to think about. You may appreciate a larger grill when your father has you all over for a cookout
