Thanks Brian. I just found this online about pricing -
"The X-ONEi offers an option between the existing FasTrak SuperDuty (residential) and the current X-One commercial model. It offers new cutting widths of 52 inches and 60 inches. The smaller horsepower engine and some size differences provide a lower-priced alternative to the X-ONE, while still offering a commercial cutter. The X-ONEi also features a new Parker transmission. Excel says the X-ONEi 52-inch model will have an “aggressive” MSRP of $8,870."
