I can't seem to find those nice old sewing machine cabinets here (Az.), wish I could. modern large T.V. stands work ,some need reinforcing But, do tend to be a bit short when playing them standing up.
you can buy a metal type stand (home depot ,ect.), then just bolt on wood sides, & what ever you want for the top. Tiss my plan. already found a few nice pieces of Oak wood for tops & a few pieces of granite also for the tops. found these cheap enough at good will stores.
now old church style pews that the man of the cloth reads from ... are very nice too. tend to be little big ,a lot heavy. seen a fair amount of these but, cost plus shipping... !!!
