I have a 10" Meade Schmidt-Cassegrain LX200 GPS guided telescope. For those unfamiliar, a 10" telescope is huge. This is not a telescope you tote out on your back deck on a whim... it's for serious astronomers, so bear that in mind. It would come with an astrophotography setup with a heatsinked camera and color filters, hard shell case, tripod, a bunch of optical lenses of various magnification, focusing reticule, equitorial wedge, sun filter, moon filter and lots of other miscellaneous stuff.
Shipping weight far exceeds 100lbs, so in person pick up would be best, but I will ship if necessary and price can be agreed upon. This scope has been supercharged by Dr. Clay at the Arkansas Sky Observatory. (http://www.arksky.org/supercharge.htm
All in all, this scope and accessories cost over $8000, I would consider selling in the $4500 - $5000 range + shipping. Just the base scope, if you went out and bought it right now is $4000 with shipping.
I am willing to entertain offers as well. It's been sitting in my garage for more than a year and I just am not going to have time to do any serious sky watching anytime soon... and they've built up a lot around where I live, so my light pollution index has gone through the roof. This scope is cleeeeeean. The only real issue is the targeting scope has the crosshairs melted. Once, when I was doing a bit of sun gazing, I forgot to cover the targeting scope and thus over heated it and melted the crosshairs a bit before I realized what I had done.
