I recently picked up a second 100mm ED OTA (Saxon) for just under $1000 (on sale) at Optics Central in Melb. They're light, easy to mount and give a sharp contrasty view. I've had a 10" SCT, various dobs & newts of 6 - 10" and I think the ED100 gives as good a look at the planets of any of the scopes I've had. They might not quite have the resolution on globs and nebula and galaxy hunting as the bigger scopes, but the view - in my eyes - is always sharper and more pleasing. Cool down times don't seem to be an issue and the smaller refractors of this size always seem to be less affected by mediocre or poor seeing - I'm sure other people's mileage will vary but I think they're a top choice.
