Reddit reviews Double Piano Keyboard and Laptop Stand by Griffin | 2 Tier/Dual Portable Studio Mixer Rack for Turntables, DJ Coffins, Speakers, Audio Gear and Music Equipment | Deluxe & Versatile Steel Construction

I gig with a little more gear than you, but I fit it all on a cheap X folding stand with a metal shelf I found in the dumpster across the top for a table. The shelf is a rectangle of sheet metal bent around the edges for rigidity. The stand is a little lower than it should be for good ergonomics but its worked for me, gigging about 3-4 times a month for the last 4+ years.

I recently bought a Griffin coffin stand like this one:

and modified it so that the legs extend further so the table is higher. I haven't gigged with this stand yet because I threw it in the studio and started using it there. Its now too useful to leave folded up next to the door...

i'm thinking of getting [one of these eventually] (http://www.amazon.com/Double-Studio-Keyboard-Laptop-Griffin/dp/B004THB8OW/ref=sr_1_63?ie=UTF8&qid=1398177831&sr=8-63&keywords=keyboard+stand+tier) as i want to put the keyboard on top, and my huge keyboard case on the bottom spot, with my desktop synths/sampler/noisemakers/mixers/whatever on top of the case. seems very sturdy and folds up surprisingly small.
