Alesis Andromeda A6

I am thinking about buying an andromeda but I have a few questions first

I will only be able to spend around $1900 - Do you guys think that I
will be able to find one 2nd hand in good condition for around that
price easily?

I am selling my beloved (but not very analog sounding) nord lead 3 to
buy the A6- but I can't  sell it unless I am %100 sure that I can find
an A6 in that price range.
I have seen them go on ebay anywhere bettween 1600-2500 so I am
confused as to what the adverage 2nd hand andromeda goes for.

also - this will be my only synth for a while, do you guys think it
covers enough sonic ground to be the only synth I have?
I am going to buy more but this is going to set me back a bit.

I make new wave,electro,dance and industrial.
from what I have heard it can cover all those sounds well.
also
are there any known problems I should look out for with this synth?

thanks
