I'm 5'11", so i feel your pain. I do amost all of my cutting on the kitchen counter. it's just the right height.
this link shows the folding/rolling cutting table i hope to buy within the next couple of months. i plan to get two so i'll have a nice huge surfaces for the basting and machine quilting phase. i haven't shopped around yet, so don't know if this is the lowest price source.
