Glad the PreSonus is working for you. I had a FireBox, that when my Firewire equipped laptop died, it rendered it a bit useless to me as firewire equipped lappys are nearly non-existent these days - well, at reasonable prices.

that's when I bought the US-800. The rest of the US-x00 product line lived for several years, but the US-800 disappeared from the market in the fire sale that you and I bought in (got it for $99 from Musician's Friend, correct?). The price should have warned me that there was something wrong - as the lower channel count versions were selling for more than double that price.

I might go for the lower end Audiobox.
