This thread seems to have the topic covered but in hindsight they
don't come in any cheaper.
I'd go for the
Roccat Apuri simply because of the USB hub though if you want a DIY approach to a seemingly mind bending issue, simply pick up a binder clip
attach it to the edge towards the back of your desk/table top while you run the wire for your mouse through the clips and with a cable tie lock the wire in place albeit with some slack between the mouse and the binder clip.
