Whats the difference between the top three 5 speeds

Just remember both of the these transmissions will not be available until May-Jul...

Keisler say they are selling so many the soonest I could get one would be May.

Passon said his will be available when 100% of testing is complete which would be this summer.

Kinda tough predicament do I buy a Keisler for $1300 cheaper but have to find out what parts I need if anything goes south? Or buy a Passon which is more pricy but if something goes wrong I can always head to Napa and pick up a direct replacement?
