Ron Andrews over at RMR has a 25th scale Komatsu excavator. It runs about 90 or 95 bucks, I got mine so long ago,I've forgotten, to be honest with ya. It's still listed in his website, and it IS a VERY nice model when it's done. It doesn't SAY it's a Komatsu, but it sure looks like one. it also resembles that Cat excavator too, so maybe with a deft hand at painting or decaling, you could make it either! Hth.
