Quite long and informative.
I've got one myself but havn't tried it with outboard pre's. I've recorded a six mic drumkit + bass (hi-Z input) and guitar all at once, all in 24-bit... it's awesome and very easy to use. Except for one thing. I spend quite a while reading manual trying to figure out how to save a project - I still don't know how to do this but it does save your work when you use the protect function.
Oh yeah, one more thing - it fits beautifully in my backpack thumbsup
