Casanova for US 3000 or Casablanca 1 for US 2700

Well.. once again... this choice make me confuse.. help me out guys...

Thanks a lot for your kind attention & help.
I would opt for the CB I if you think you may want to upgrade the internal components to the current CB III. Otherwise, I would go with the Nova. The operating system in the earlier CBs leaves a lot to be desired. I owned a CasaNova prior to buying my CB II and thought it sounded great. I hope this helps.
Thanks for your help... got the casanova already... CB I with upgraded to III is way to expensive for me at the moment..
