I do not know who will do this, but I personally would like to see this chart filled in completely, with the information that is missing. I would also like for someone to add a column of 1 or 2 websites, per motor, for best current purchase price and try to keep it updated. For example, I have seen many different websites that sell the Netgain Warp 9 motor ranging from $1,600 to $2,000
