[APML]: Astrophysics 600 Mount vs 900 Mount

[<mwcook@concentric.net>]

   I've been debating the merits of two AP Goto mounts;
the 600EGTO vs 900EGTO.  Currently I have the older
AP600 mount (non E), AP 130mm F/6 scope with 80x900
guidescope and ST-4 autoguider.  I have a fairly dark
site so portability is not a big issue.  

  - Does anyone think that the 900 mount would be
    worth the additional $1500? 

  - Any idea on the resell value for the the older
    AP600 mount with pier? (upgraded for ST-4 interface
    and checked and aligned by AP)    

   Thanks,
