If you find you outgrow the number of inputs, you can get something with the same or a few more and 'daisy chain'...use the little one as a submixer and plug it into 2 of the other.
In my home studio, I have a Peavey8 (a little bigger than the one markb linked to) and a Yamaha MG10/2 that I use independently or chain, depending, that go into powered monitor speakers and/or into my DAW.
I prefer having that many inputs so I can leave things hooked up and preset, ready to go, instead of reconnecting and resetting levels.
EDIT: added this photo to show you the default hookup scheme..under each mixer is a Samson C-Valve Tube Pre I use in a variety of ways:
BTW: They both use external power supplies.Either of those mixers can be had used, in good shape, for around $75.
