Was wondering the same thing last year. I ended up getting a 5 in 1 with a stand and case off EBAY for around $40 with shipping. I think this is the same set (below). Since I don't have a third arm either, I thought this was the way to go for me. Everything apears well make and the auction price was less than purchasing directly from Amvrona (comes from same place). I have only used it once since surgery to leg has kept in my chair a lot the last year.
