Hey Rick,  
 
There's a cool '75 fretless Ripper for sale here:

At $795, it's alot more reasonable than what any other similar era Bass sells for.

I should make a slight correction.  This Bass should be up there on my list of all time favorite Basses as well.  This was my first ever Alembic and what made me fall so in love with all Alembic products and the wonderful people who make them.
 

 
Still the best sounding and growliest fretless in the world - If Jaco was still around, I think he'd love it too.

thanks to everyone, for their input regarding the pre ernie ball  stingray.

Hey, Hodge!
 
Glad you found the info helpful ;]
 
Have fun! Mike, tho
