Need A New Mixer... Options

[nachojoker]

right now i dont have a mixer that i use before going directly into my gadgetlabs recording interface. i do have a Peavy 6 channel powered mixer, but it doesnt have 6 outputs. my gadgetlabs box has 8 ins and 8 outs, but there is no master out. how can i monitor all the outputs at once?? also, i guess there is no way to boost the input signal going into it without a mixer or preamp, is there a good low budget 8 in/8 out mixer i can use to mix the drum mics/bass/guitar, etc?
