You can't expect much choice in the 24" size; at this point it's purely a replacement market as 27" and 30" ovens are always used in new construction if built-ins are installed. I've seen many situations where an older cabinet face can be discreetly re-cut to accept a 27" oven, and have in fact done it myself. You might consider this as you'll find a much better selection in 27" ovens.
