The only time I see really cheap or free scopes is when some one wants me to fix em up for them, lol.Typically 60mm scopes found at yard sales.Occasionally a 4.5 (twice) both of those were donated to others who I work with.
Id love to find 10 inch scope for 20.00 locally (never happen) here in lake effect north east Ohio.

It has an upgraded mirror cell and it looks to me to have an upgraded focuser.
I'd clean it up and take it for a spin to see just what you have. You might be surprised and have a real gem.
You could use it the way it is for a while. If the images are good and you have the inclination you can make it into an light weight travel scope.
My old red 13.1" Coulter works fine with the original mirror cell and a new focuser.

Gary,
Wow - a blast from the past! I bought one of these in 1982. For a 10" 'scope it was pretty massive, and that original primary "cell" was a joke. But it was true to Dobson's form!
This was a sample of the relatively new "thin mirror technology" which saved weight but made the primary more warp-prone - especially with that Flintstone mirror cell. Sadly, my primary was anything but "precision". Nice for deep-sky objects but not much else (it had worse resolution than my 4" Edmund Astroscan). I'm not saying that the primary in your sample is as, er, "mediocre" - but don't be too disappointed if it is. These were essentially cheap, mass-produced 'scopes (I paid around $300 for mine brand new - an amazingly low price for a 10" back then). However, if yours has a superior primary cell that should help.
Another problem is collimation. If yours has that single flat crossbar secondary mount, beware. Kind of hard to achieve precision adjustments[!}.
Still, for a good-sized light bucket at $17 it's hard to go wrong. And if you're at all mechanically inclined you can really spiff it up.
I don't know if these 'scopes have achieved any kind of "cult" or collectible status, but if they have you may possess something even more special there.

I think these old odyssey's get a bad rap, the mirrors on both mine are pretty good. Good for deep sky anyway.
Albert, that's good news. I never had a chance to look through any of these scopes before. I glad I found something useful for at least visual work. 
Last night before getting fogged out, I set mine up on Jupiter, and at 475x got a very nice view of bands with little white dots on them.
Not just DSO's. At least some of the Coulter mirrors do quite well on planets as well.
