I recently got an older model Billy Goat TR1104 from a former landscape owner, Its very lightly used and very good condition, it starts right up and seems to run fine. I wont be able to use it until the fall, but the seller told me to use it, see how I like it and then talk a price. He mentioned that he was gonna post it online for $1000, but gave it to me because I am a close friend. I am just wondering what you would value this machine? I'm trying to be fair for both of us, here are some pics.
