Korg Poly800/EX800 Users

I just recently acquired a Poly 800 as part of a deal when I sold my 
Octave Cat.  I've messed with it a bunch, but it just doesn't do the 
trick for me.  On the other hand, it doesn't seem like it would be 
worth selling, so what I'd like to know is, are there any mods out 
there that I can do that don't require much knowledge in electronics?  
And can I do multiple mods?  So far the only ones I've found online are 
the Moog Slayer and FM-800 mods.  I've listened to some samples, and 
they sound good, but I'm wondering what else is out there.  Any help 
would be greatly appreciated.  Thanks.
