If you're comparing to $3500, you're looking in the wrong place. The 
6.7" motor I referred to is less than $1000 from KTA. Similar motors can 
be found used at the EV Trading Post for $500-600. This one is 15HP:

(Bear in mind that I would recommend this class of motor only for those 
who would be content with 45-50mph top speed, in a very small car. An 
ImPulse 8 motor, appropriate for more general use, can be had for around 
$1300 new.)

Being frugal can certainly help to lower the cost of a conversion. 
However, given the quantity of money typically involved in getting a 
vehicle to run on batteries, it is wise to be very selective about the 
parts on which you choose to save money. For example the controller, 
being more easily replaceable, would probably be a better choice than 
the motor (which incurs fabrication costs for the adapter plate, hub, 
mounts, etc). Also include the value of your time and effort, and 
disappointment when a component that is too small ends up burning up 
prematurely, demagnetizing its field magnets, etc.

Certainly no problem in making your own choices, and trying things that 
are not common. I just encourage everyone to look at what's out there, 
and take an extra careful look when deciding against tried-and-true 
approaches.

I think you're certainly in the category of people who could deal with 
the issues involved in experimenting with a motor like this, knowing 
what you're getting into. However in my opinion, posting a generic 
recommendation as a "good motor" with no accompanying explanation 
presented an opportunity to clarify for the benefit of others who may 
not be looking at a conversion project from the same perspective.
