Grill purchase

So I bought a grill today that was on sale. Do I have buyer's remorse? Probably. I tend to feel ill when I buy things regardless of the rationale for the purchase (I read a lot of reviews on Lowe's website in addition to the rating of Consumer Reports. Heck, I even asked a guy I know that bought the deluxe version  of the grill for his opinion. No one deterred me from making my less than impulsive purchase).
In the grand scheme of things, grilling is a luxury. Old grill was a gift that merely set us back the price of the propane tank. That was at least 5 years ago. Got a lot of use out the grill, but I feel the need to log all of the new grill's usage. Maybe I'll make a spreadsheet of the cost for steaks and such made and cross reference with a comparable restaurant until I feel I get my $ worth for the grill.
Even could keep track of burgers made on the grill. Steak N' Shake will be hard to beat price-wise with Kids eating Free on Weekends, their $3.99 meal menu, and their bombardment of coupons.  We ate there yesterday for lunch and the meal cost a whopping $13.02! That's including drinks, soul, and milkshake.

A pound of ground beef costs X. A quart of ice cream costs Y. A bag of buns costs Z.
