I'd have to agree with Phil here "O". If you are after goto that is portable and still give good deepsky views then an 8" SCT/Mak would worth serious consideration. Meade LX90/LX200 (8 or 10" though the 10 is definately heavier than the 8) or Celestron in the same range. Alternatively consider an 8" Dob with an Argonavis.
Get on up to Astroron's at the next dark of the moon and you will get to try scopes from 80mm up to 400mm, refractors, Newts and SCTs.
