our lab does essentially the same thing, but since it's a lab of over 20
people where almost everyone uses the GeneClean protocol once a week or so
(on average), we avoid the wrist falling off problem by just buying the
Glassmilk and having our work-study student make up the rest of the
solutions, more or less as described here.  works pretty well and is still
quite a bit cheaper than the total commercial version.
