Alesis Andromeda A6

i'm considering getting an andromeda but i've crept around a little 
on the code404 archives and seen a few bugs reported with the older 
versions of the andromeda. is getting a new one advisable because of 
this or is there really no difference in the manufacturing between 
the first batch and the most recent ones available in shops? is there 
a certain os version i should be sure to have? 

thanks,
gm
