What's a Trac Vac 880 worth?

[Fuddyduddy1952]

I have a Trac Vac 880 I'd like to sell, don't know what I should ask for it. It runs and works well. I have the Trac Vac mower attachment, a universal plastic one, 40 feet of extra 8 inch hose (I'm thinking that alone was about $200-$300). I made a dolly for the front which works great keeping it from tipping over and keeps weight off of tractor hitch. I bought 8" PVC cutting in half, two 5 ft. sections one I put handles on it to vacuum leaves by hand.
I bought a Cyclone Pro for my JD 455 so I don't need the Trac Vac. Cyclone I used first time today.
Thanks!
