Sorry, Mike, but I don't even know where you could find a grey market dealer in my own area. The only grey market equipment I've even seen (and very few at that) in my area came from auctions or major dealer trade-ins.
There is a dealer list thread in the Yanmar forum. I think there are several gray dealers in your area. The list isn't brand new and gray dealers come and go but it is a starting place.
Many of our customers decide to go with the 1 bottom plow and lift disc harrow--combined cost is under $700 new--You would also have 2 tools that will be used on more projects thru the year and probably can be easier to justify--Ken Sweet
