spirit notepad mixer

["diatom drone" <skincage@infin8ty.com>]

i'm looking for a little sub-mixer to use for feeding samplers and/or
experimenting with effects routing in addition to my existing mixer. of the
choices this seems to be a pretty handy device but i don't know anyone 
who's
owned one. can anybody give me some idea of the quality, ease of use, how 
it
stacks up with stuff in its class etc?

thanks!

Jon
