I have had a Big Green Egg for about 2 yrs now.
First off, you can see & taste a HUGE difference in the food. I'm not someone who enjoys cooking or grilling. In fact I used to hate it. I sucked at it & the food wasn't all that great when I was cooking on a gas grill.
The secret to the egg is that its made of ceramic. The heat retention & the ability to control the temps ranging from 200 degrees to 700 degrees. I've cooked pizza, bread, steaks, hamburgers, pork chops, ribs, chicken, whole turkeys & just about anything you can think of.
If you've ever bought something that was supposed to be top of the line & got it home & had it only disappoint you b/c it wasn't as great as you thought it was...well the Egg isn't it. I agree that $1000 is a stretch to pay for a cooker. Everyone calls the Egg a grill but its far from a grill. Its a smoker, grill & dutch oven all rolled into one just by changing the setup inside the egg.
My neighbor behind me paid over $700 for a stainless Weber gas grill. After eating the pork chops that I cook, he immediately give his Weber to his parents & purchased an Egg.
I carried some left over chicken to work & a couple people wanted to taste the food that I had cooked the previous night & now they have an Egg.
My father-in-law is one of these people who pride themselves on being able to cook. He only cooks in a Weber charcoal grill & said that there was nothing even close to cooking on his charcoal briquets. He cooked ribs one night & when he asked how they were & my wife replied they were "alright", he got pissy & wanted me to cook ribs. I smoked some ribs on the Egg & even he admitted that my ribs smoked his.
I honestly have never tasted pork chops better than the ones I cook. All I do is heat the egg to 400 degrees, 4 minutes each side & chow down. They're spectacular.
I'd say spring for the Egg. You won't regret it. I've turned about 5 people onto the Egg & not one of them have regretted the purchase.
