I would also say to keep both...personally, if
you had to get rid of one, I would give
the slight nod to keeping the 4000, but
towered 1200's can be just as cool.

Soft Hut had a few of those DSP 3000's for sale
a while ago. Thinking back, I wish I could have
jumped on one of them for collector's value...
but they were just too expensive.
