Yamaha DTXpress/DTXplorer/DTXtreme

thanks for the info chaps, much appreciated

I found a STAGELINE MMX-4 and judging by its description it sounds 
like what I need, although its seems quite cheap (only £20). It has 4 
mono inputs, no stereo and no extra features whatsoever. I'm not 
particualrly bothered about adjusting panning and gain settings, just 
want to mix my brains and a CD player through one single headphone 
output for practice. Would this do my job or is there some sort of 
catch? 

Heres a link if anybody wants to have a look:

Not familiar with half the technical specs, are they particularly 
poor? 

thanks again
