well when you do find a buyer and need to ship it, go fedx ground. I sell alot of stuff (including saddles from time to time) and the heavier stuff goes fedx. UPS charges $60 + and I can pack about 25lbs (a little more or little less) in a HEAVY cardboard (I pack stuff up good and tight) box, with whatever is inside wrapped twice in plastic and packed to the hilt with bubble wrap or styrafoam and it ships anywhere in the lower U.S. For around $20 bucks.
Don't use the UPS express stores like Pack N Mail or places like that - you will get charged double because they have to make a profit to support the store. Go to your nearest FedX center (distribution/shipping) and send from there. Tracking and insurance for up to $500 won't cost any extra.
