As others have said - Weber is the way to go. Ducane is also good for the price and owned by Weber, but they are made in China - whereas Weber's are made stateside.

Regardless of the brand you end up with....the simple most important thing is BTU output. If you are going to grill premium steaks, you want that sucker as hot as you can get it (and not have to wait forever to get there). 700 degrees plus as a starting point for a 3 burner grill.

Good luck!
