Luckily, I still have the Martinic Model V from back when it was a legitimate freebie. Given that it suddenly disappeared from every server that had previously hosted it, I'm guessing that part of his terms of employment with Arturia was that it be pulled from all distribution. I'm sure they didn't want to compete with a freebie that had 99% of the same features as their $149 product. 
 
Fortunately, nothing ever truly disappears from the internet.
 
The Hollow Sun library is pretty good for, IIRC, 25 bucks. As a general rule, sampled organs don't give you the same tonal scope as a synth-based emulation, but this one throws in the standard Kontakt Leslie and chorus effects to make up for any sonic limitations.
 
There are also some free samples out there if you google "Vox Continental samples", but I haven't tried any of them.
