Elektron Musical Instruments

Hello,

I love the sound of the SID - which really was the first "synth" I 
ever owned.  Problem is, I'm cheap, and the Sid station is getting 
horribly expensive ($950).  Has anyone pursued any of these 
alternatives? (yes, it is heresy to bring this up on the elektron 
page... I know).  I could buy a used one... but these look pretty 
attractive.

Quadrasid VSTI?

Hardsid Quatro PCI?  Four sids, one PCI slot - sounds good to me!

Midi Sid? (cheap, tiny, and a fun project? - build the controller 
too, and it looks much like the Sid Station)
