Chris Martin has a Coote.
To my knowledge, it is a 2 wheel grinder,,similar to a Grizzly
http://www.grizzly.com/products/Knife-Belt-Sander-Buffer/G1015.
The Coote doesn't come with a motor so you can put on the kind of moter you want or have. I think that you can put a belt and step pulleys in order to control the speed. You can set the drive mechinism up how ever you want.
For the money and versitility the NWG (No Weld Grinder) is the way to go. Tracy at
www.usaknifemaker designed this grinder and sells the plans and all of the parts needed to build one.
I conduct workshops to build this grinder, with several modifications. You can check my previous posts for more information on the workshops.
Considering where you are in relation to me, North east Tennessee you will probably be better off getting the plans and parts from Tracy. At this time I don't have any workshops set up in your area. I am conducting a workshop and then teaching a class in May at the New England School of Metalwork.
