Make sure that you get it made so it is at an ergonomically correct height for you when your machine is dropped in. If you are shorter than average , then the standard working height of 29-30" (when machine bed is level with table surface) may be a little too high and will cause neck and shoulder pain. I made a small table using metal legs that are adjustable in 1" increments to hold my PQ1500s and it's extension table, then I butted them up in the ell between two height adjustable folding tables which gave me good support to the left of and behind my machine for quilting large quilts.
