I sure hope you purchased the BlueStar. Fabulous stove and cook top. You can get any configuration you want. By now, you have already purchased something. Hope you are enjoying whatever it is.
I don't know that any of them make a 46" stove. As for other sizes, there's lots of old discussion here available via the search function. And THS over at Gardenweb is also a good place for lots of range debate.
