Schick E2

I will be receiving one of these razors from a trade I made soon. Can anyone shed any light on how it might compare to the Cobra classic since the Cobra is the only other SE razor I have used. Also, what is the value of one of these things, 5-10$? Just curious as I might look into giving it to a friend to start wet shaving with.

Edited to add I just saw the wiki on all the Schick injectors
