Under my Teres 320 I've been using a three-inch thick, two-foot square maple from Tony's Woodshop (look under multimedia storage). Its not Amish, but a few yrs ago it was ~$75 w/ shipping. The maple block sits on doubled-up corrugated-rubber-and-cork pad thingies like Mapleshade sells, but got them much cheaper, example here: http://atlantavibrationpads.com/rubberandcorkpads.aspx
