Treadmill desk advice sought

After reading Neal Stephenson's essay on using a treadmill desk in Some Remarks, I've decided to try it for myself. But I don't want to ditch my beloved desk (a wooden kitchen table) — instead, I was thinking I'd raise it on blocks to standing height, get a treadmill, and wedge the handlebars under the desk so that I could walk while using it. Does anyone have any recommendations for a treadmill model? It looks like it's really hard to use a manual treadmill without holding onto the handle-bars, so I'm guessing that means I'll need a motorized one. But motorized treadmills all seem to have their controls in the front, which I envision wedging under the desk, rendering them inaccessible. Have you tried this? Got any ideas? I think I probably want something like this, but available in the UK, and cheaper if possible.
