Here's a way of looking at these things that makes sense to me. Multiply any drive's rated current by its rated voltage. Divide that number by its price. Do that with a G201 and you get 4.9 (7A * 80V / $114). Do that with the Cheap Drive and you get 5.0 (3A * 50V / $30).

Those numbers gives you the relative value of any drive; how much performance you get for the money you spend.

By the way, midband compensation and a smoothness trimpot are now included at the same target price. It just worked out that way; it fit in the CPLD so it got included in the drive.
