Speck X.Sum Line Mixer

[philly]

Hi all...
I'm just going about the process of simplifying my life.
I've previously been using a crap 32:8 mixer (the "B" one!) with an assortment of Keys, Guitars etc. into a computer. I generally bypass the desk when recording and only really use it for mixing midi/soundcard signals. So I never really use the faders, pans, eq, aux's.
Would one of these line mixers be the go?

Are there any drawbacks I havent thought of? Anything else I should be looking at?
Cheers for any advice
Phil
