Here is a picture of the sewing table I just ordered. It is actually a school computer desk with a dropped section for the keyboard, but it works perfectly for my machine.
I got it from epicofficefurniture.com but I called to place my order because the drop-out can be left, center or right and the online order did not allow me to specify the right hand position.
It comes in several colors and in 30" by 48", 30" by 60" and 30" by 72". It does require some assembly and is very heavy!
It is shipped by a truck due to the weight.
