hmm ... i probably shouldn't be labeling the treadmill posts as 'brawn'. the treadmill desk is pretty much a direct mapping of 'brains and brawn'. i.e. i like it.
couple minor tweaks this weekend. i put some high grip contact paper on the desk shelf to keep my keyboard from sliding around. that was getting annoying. also, found some small bungie cords to secure the wire shelf to the treadmill frame. the wire shelf is light, so the bungie cords have made it a little more stable. started with the cheap $35 wal-mart shelf. lowes has a shelf with the same measurements for about $75. but the lowes model has thicker legs and is heavier; i might switch to that one to get even more stability.
