Hi! I kind of like the concept, sort of like a Kelly Blue Book for mowers. Only problem I could see would be who would determine the values as everyone has their own opinion as to a mowers value. As a Lawnboy guy I kind of have an idea of the value of my mowers both as a collectible and the value to me personally, but I would have no idea of the value of other brands of mowers and could therefore not offer my opinion on other brands. Also you can tell by sites such as eBay that many sellers think their items are worth their weight in gold by what they are asking for them even though the fair market value is much different. Don't give up on the idea, however, as I think it would be a great reference point to start when shopping for a used mower or selling one. I had posted recently myself asking the members for their opinion regarding the value of a 5273 Lawnboy I was thinking of selling and it was helpful to know how much they thought I could sell it for. Thanks and keep those great ideas coming. Bill
