I picked up a table today at Guitar Center. This is actually a "Trap Table". It is designed to hold rythem instruments for a professional percussionist. The table comes in two parts - a height-adjustable chrome plated stand, and the table top which is 22" Wide by 16" Deep. It has a 1" tall rail going around the perimeter, so props won't roll off the table. Seems to be very sturdy and well constructed. It was $96 including tax. I'll add a padded black velvet closeup mat to the top to give me the desired working surface.
