Im a bit confused on the powered and non powered mixer thing...not sure what I need.
A powered mixer simply means it is both a mixer and a power amplifier for your loudspeakers, whereas a non-powered mixer is simply a mixer that woks at line level signal elvels like all the rest of the equipment in your chain, and you'd still need a seperate power amplifier to drive your speakers (or speakers that have their own amplifiers built into them.)
In general, powered mixers are designed for live PA use, with the amplifier meant to drive the PA speakers and/or stage monitors. In general these are not the best choice for use in recording because - while there may be exceptions - mixers designed for live/PA use tend to be noisier or less audiophilic-sounding then their studio non-powered bretheren. Also, many powered mixers designed for this purpose have only mono amplifiers in them instead of stereo, meaning you couldn't use those for your studio montors if you wnted to actually monitor your mix in stereo.
I'd just stick with a standard non-powered mixer (if I went with a mixer at all - see below) and let your monitors either power themselves or work off of a seperate amplifier.
But I also gotta ask, why do you want a mixer at all? Do you have a specific plan, or are you looking at a mixer just because you think that's what you need to do? What are you recording *to*? Are you recording to a seperate recording device, or to your computer? If you are just recording two channels at any given time, I'd skip the cheap mixer and just go with a decent two channel preamp/interface, something like
the Tascam US122L for example. It'll give you all the level control of a mixer, will still handle two channels at once the same way, comes with quality name-brand recording and mixing software, and will usually have better quality mic preamps (quieter, cleaner) than your average sub-$100 mixer.
