for +15 Grand you can afford a ladder ;-) actually they are working on ones shorter focal length but still large aperture.
@hamei: to me, the idea of spending a so much money on light gathering, only to substitute a technology with such poor low light performance in place of my eye doesn't make any sense. people have put webcam's on them but it's just not right... astrophotography is though as well since they lack an equatorial mount for low-noise tracking on long exposures.
besides there are shorter ones that are more affordable, and portable which is something that's very important is you don't live on a low light pollution tract of land. This is my most likely Dobsonian purchase http://www.obsessiontelescopes.com/telescopes/22UC/index.php
