Where can I find a simple audio mixer below 100$?

I want to be able to use 1 pair of headphones for my computer and digital piano simultaneously so I can stay entertained on the computer while I practice piano. I have to use headphones because I live in an apartment and can't make noise. Switching headphones between the two gets really tiresome and discourages me from practicing as much.

I want something like this http://www.amazon.com/gp/product/B0002D03AW?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00, except powered and without too much volume reduction. I bought this and found that the volume reduction made it unusable for me. I can barely hear my piano when I use these.

Every other mixer i see through a quick skim of amazon is either too complicated or too expensive. I need one without the drawbacks of that one I linked.
