Does anyone have any links to commonly used motor resource?

I am trying to compile a list of motor related information to help sort out the differences between the various motors used by electrathon teams. My challange is that when I get to a vendor site like http://www.cloudelectric.com/category-s/14664.htm or https://shiftev.com/index.php/test-vmart/motors-2014-01-09.html it is daunting to sort thorough all lf the available options.
Does anyone have a good starting point for sorting out the mass of data?
Thanks
David

I would start by searching by DC HE motors, CloudElectric makes that easy, then search by voltage. Are you searching for a motor for your team?

I am looking for two reasons.
I currently test with a ME0909 I got as part of a electrathon starter kit last year. Now I am looking for a second more efficient motor so that I can run comparisons between the two. I built a homemade dynamometer which I would like to determine if it is accurate enough to determine small differences between motors.
I would also like to create some sort of table so new people like me can get an overview before digging into the details.
Thanks

Mostly everyone runs Briggs and Stratton Etek motors. If I had the money (hopefully later on) I'd get a Lynch or Agni motor. Both are the same thing, just the Lynch is made in the UK while the Agni motor is made in India. I've heard the Lynch/Agni motors are slightly more efficient compared to a Etek. The Lynch and Agni motors are the exact same in apperance, and all three (Lynch, Agni, Etek) all share the same type of armature. The Brush housing is a different style and the motor mounting pattern is different from a Etek compared to a Lynch/Agni.

It is that phrases like, "I've heard the Lynch/Agni motors are slightly more efficient compared to a Etek." that I would like to quantify that improvement in efficiency in order to provide teams more information before they spend up to $2000 on a new motor in order to gain a few percent greater efficiency.
To borrow a phrase from Donald Knuth the renowned computer scientist, "Programmers waste enormous amounts of time thinking about, or worrying about, the speed of noncritical parts of their programs, and these attempts at efficiency actually have a strong negative impact when debugging and maintenance are considered. We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Yet we should not pass up our opportunities in that critical 3%."
This often shortened to "Premature optimization is the root of all evil."
