I would say you would get a better price on a JUNO-6 , JUNO-60 , JUNO-106 than you would on a JP-8000 .
You can get a ROLAND SH-32 for less than a JP-8000 . The SH-32 is $ 495.00 brand new and a JP-8000 is around $600 - $650 used .
You could get a KORG DELTA for around $250.00 . I like the VA synths , don't get me wrong . I have a KORG MS-2000 , OBERHEIM OB-12 , REDSOUND DARKSTAR XP-2 , ROLAND SH-32 , and a NOVATION K-STATION as far as VA synthesizers and I love them all . I think you would enjoy a JUNO or a KORG POLY-6 or a KORG DELTA . Easy on the wallet and great sounds .
