I know this is an old thread, but might still be relevant, especially considering that the Member's Mark Pro Series Gas-Assist Charcoal Grill is now on sale for $179 at Sam's Club. I bought one for $300 in June and have had nothing but trouble with arguably the most important feature: the gas-assist lighting system. The only way to reliably light the gas assist is with a lighter, which involves removing the grates. I've had three replacement igniters and one replacement burner tube, with no success. I'm going to return it.
I've never owned a
Weber kettle grill, so I can't compare its function as a cooker, but I can say that the
vortex does fit, SNS Deluxe does not. The diameter of
the kettle is 22.5" compared to 22" for the Weber, but the slope of the decreasing radius of
the kettle below the grate is such that the SNS doesn't fit.
I am considering the Weber Performer Deluxe and am curious if that feature is as helpful as one would hope. In every gas grill I've ever owned, with the exception of two Webers, the igniter would fail almost immediately, as would replacements. With my two Weber gas grills, the original igniter was still working reliably five or more years later.
If it's as solid a platform as I'd hope. There are two hardly used Performer Deluxes for sale for $200 - $250 within my area. I'm thinking I'd buy one and put in a new SNS grate to mate with the SNS Deluxe.
