Easy, make room - get rid of a family pet or wife then you can keep both :lol:
In all seriousness, I love both my A1200 and A4000 projects, I couldn't get rid of either since they have their own strong points.
It really depends where you want to take your projects as the A1200 is cheaper to PPC/PCI up whereas the A4000 versions (CSPPC/MediatorDi) are more expensive.
If you just want to get Zorro cards then the A4000 is better option as Zorro expansion for A1200T are ZII only whereas A4k has ZIII.
A4000 with a Cybervision 64/3D, Cyberstorm MkII/III 060 and Deneb USB makes an awesome setup + 16bit Soundcard like a Toccata & X-Surf NIC to live the dream :afro:
