They do not exist. Plus the venting plus makeup air for a 48” will cost more than your budget for the range. Your budget is solidly in the more capable 30” higher mid level ranges, like Cafe, with the lower CFM ventilation and makeup air that they also require. Your budgetvwould need to be 3x-10x to get a 48” and everything it needs to go with it. And 3x woukd be really stretching it thin, with scratch and dent purchases, and you doing all the labor for everything. Including climbing on the roof to install the 10” ducting, and running the bigger gas lines.

@1221cross, Check out Designer Home Surplus. I purchased a Capital rangetop from them a few years back. A friend purchased a Superiore hood last year and my brother purchased an entire kitchen from them about five years ago. All of us had a good experience.
