I use a computer table I got from work years ago for two of my machines. It is 72" long and has the holes for cords that I use. I had to remove the keyboard trays but otherwise works great. I like having the metal to stick magnets to. Height is fine for most things. Sometimes I use a balance cushion (like the Gypsy situpon) but that is more for my lower back. I have long legs and a short body. So, if you have to rais up you may want something to raise your foot controller too.
I say Go For it!!
