Do you mean a Blackstone griddle? A grill and a griddle, as rffowler55 mentioned above, serve two different functions. Several Blackstone owners we talked to stated that a Blackstone griddle is much like a cast iron pan in that they work great but require some attention to keep them "seasoned" and, oddly enough, seem to perform better the more they are used. Because we're not full-timers, we decided to get a 24-inch Royal Gourmet griddle which has a porcelain enamel cooktop and (I hope!!) doesn't require quite as much maintenance. We've only used it a couple of times but we've been very pleased so far.
